Floating-Harbor syndrome

Floating-Harbor syndrome (FHS) is characterized by typical craniofacial features; low birth weight, normal head circumference, and short stature; bone age delay that normalizes between ages six and 12 years; skeletal anomalies (brachydactyly, clubbing, clinodactyly, short thumbs, prominent joints, clavicular abnormalities); severe receptive and expressive language impairment; hypernasality and high-pitched voice; and intellectual disability that is typically mild to moderate. Difficulties with temperament and behavior that are present in many children tend to improve in adulthood. Other features can include hyperopia and/or strabismus, conductive hearing loss, seizures, gastroesophageal reflux, renal anomalies (e.g., hydronephrosis / renal pelviectasis, cysts, and/or agenesis), and genital anomalies (e.g., hypospadias and/or undescended testes). [from GeneReviews]

Cardio-facio-cutaneous syndrome

Cardiofaciocutaneous (CFC) syndrome is characterized by cardiac abnormalities (pulmonic stenosis and other valve dysplasias, septal defects, hypertrophic cardiomyopathy, rhythm disturbances), distinctive craniofacial appearance, and cutaneous abnormalities (including xerosis, hyperkeratosis, ichthyosis, keratosis pilaris, ulerythema ophryogenes, eczema, pigmented moles, hemangiomas, and palmoplantar hyperkeratosis). The hair is typically sparse, curly, fine or thick, woolly or brittle; eyelashes and eyebrows may be absent or sparse. Nails may be dystrophic or fast growing. Some form of neurologic and/or cognitive delay (ranging from mild to severe) is seen in all affected individuals. Neoplasia, mostly acute lymphoblastic leukemia, has been reported in some individuals. [from GeneReviews]

Combined immunodeficiency due to DOCK8 deficiency

Hyper-IgE syndrome-2 with recurrent infections (HIES2) is an autosomal recessive immunologic disorder characterized by recurrent staphylococcal infections of the skin and respiratory tract, eczema, elevated serum immunoglobulin E, and hypereosinophilia. It is distinguished from autosomal dominant HIES1 (147060) by the lack of connective tissue and skeletal involvement (Renner et al., 2004). For a discussion of genetic heterogeneity of hyper-IgE syndrome, see 147060. See also TYK2 deficiency (611521), a clinically distinct disease entity that includes characteristic features of both autosomal recessive HIES2 and mendelian susceptibility to mycobacterial disease (MSMD; 209950) (Minegishi et al., 2006). [from OMIM]

Aicardi-Goutieres syndrome 7

Most characteristically, Aicardi-Goutières syndrome (AGS) manifests as an early-onset encephalopathy that usually, but not always, results in severe intellectual and physical disability. A subgroup of infants with AGS present at birth with abnormal neurologic findings, hepatosplenomegaly, elevated liver enzymes, and thrombocytopenia, a picture highly suggestive of congenital infection. Otherwise, most affected infants present at variable times after the first few weeks of life, frequently after a period of apparently normal development. Typically, they demonstrate the subacute onset of a severe encephalopathy characterized by extreme irritability, intermittent sterile pyrexias, loss of skills, and slowing of head growth. Over time, as many as 40% develop chilblain skin lesions on the fingers, toes, and ears. It is becoming apparent that atypical, sometimes milder, cases of AGS exist, and thus the true extent of the phenotype associated with pathogenic variants in the AGS-related genes is not yet known. [from GeneReviews]

Cleft lip/palate-ectodermal dysplasia syndrome

Zlotogora-Ogur syndrome is an ectodermal dysplasia syndrome with characteristics of hair, skin and teeth anomalies, facial dysmorphism with cleft lip and palate, cutaneous syndactyly and, in some cases, intellectual disability.The prevalence is unknown but to date, less than 50 cases have been described in the literature. Caused by mutations in the gene PVRL1 (11q23-q24) which encodes nectin-1, the principal receptor used by alpha-herpesviruses to mediate entry into human cells. Transmission is autosomal recessive. [from SNOMEDCT_US]

Noonan syndrome 12

Noonan syndrome (NS) is characterized by characteristic facies, short stature, congenital heart defect, and developmental delay of variable degree. Other findings can include broad or webbed neck, unusual chest shape with superior pectus carinatum and inferior pectus excavatum, cryptorchidism, varied coagulation defects, lymphatic dysplasias, and ocular abnormalities. Although birth length is usually normal, final adult height approaches the lower limit of normal. Congenital heart disease occurs in 50%-80% of individuals. Pulmonary valve stenosis, often with dysplasia, is the most common heart defect and is found in 20%-50% of individuals. Hypertrophic cardiomyopathy, found in 20%-30% of individuals, may be present at birth or develop in infancy or childhood. Other structural defects include atrial and ventricular septal defects, branch pulmonary artery stenosis, and tetralogy of Fallot. Up to one fourth of affected individuals have mild intellectual disability, and language impairments in general are more common in NS than in the general population. [from GeneReviews]

Autoinflammation, immune dysregulation, and eosinophilia

Autoinflammation, immune dysregulation, and eosinophilia (AIIDE) is an autosomal dominant disorder characterized by onset of severe atopic dermatitis and chronic gastrointestinal inflammation, mainly involving the colon, in infancy or early childhood. Affected individuals tend to have asthma and food or environmental allergies, as well as poor overall growth with short stature. Severe liver involvement has also been reported (Takeichi et al., 2021). Laboratory studies show increased eosinophils with normal or increased IgE levels, as well as evidence of a hyperactive immune state, including increased erythrocyte sedimentation rate and C-reactive protein. Treatment with JAK inhibitors, such as ruxolitinib and tofacitinib, results in dramatic clinical improvement (summary by Gruber et al., 2020). [from OMIM]

Variegate porphyria, childhood-onset

Childhood-onset variegate porphyria (VPCO), also called 'homozygous' variegate porphyria, is a rare disorder of heme biosynthesis characterized by severe PPOX deficiency, onset of photosensitization by porphyrins in early childhood, skeletal abnormalities of the hand, and, less consistently, short stature, impaired intellectual development, and seizures. The term 'homozygous' refers to the presence of mutations on both alleles of the PPOX gene, resulting in earlier onset and more severe manifestations than those seen in variegate porphyria (VP), a low-penetrance disorder inherited as an autosomal dominant trait (summary by Roberts et al., 1998). Heterozygous family members of VPCO patients are usually clinically silent, but symptomatic heterozygotes have been reported (Mustajoki et al., 1987; Palmer et al., 2001; Kauppinen et al., 2001). Nomenclature 'Homozygous' variegate porphyria was so designated before the molecular defect in PPOX was elucidated, on the basis of severe reduction in PPOX activity (between 5 and 20% of control values) compared to that seen in variegate porphyria (approximately 50% reduction), in which autosomal dominant transmission had been observed. It is probable that most cases of 'homozygous' variegate porphyria actually result from compound heterozygosity for PPOX mutations (Frank et al., 1998; Palmer et al., 2001). [from OMIM]

Hyper-IgE recurrent infection syndrome 3, autosomal recessive

Hyper-IgE syndrome-3 with recurrent infections (HIES3) is an autosomal recessive immunologic disorder characterized by childhood onset of atopic dermatitis, skin infections particularly with Staphylococcus aureus, recurrent sinopulmonary infections, and increased serum IgE and IgG. Patients are susceptible to bacterial and fungal infections, including chronic mucocutaneous candidiasis. Immunologic workup shows impaired differentiation of CD4+ T cells into T-helper 17 cells, decreased memory B cells, and often decreased NK cells (summary by Beziat et al., 2018). For a discussion of genetic heterogeneity of hyper-IgE syndrome, see HIES1 (147060). [from OMIM]

T-cell lymphopenia, infantile, with or without nail dystrophy, autosomal dominant

Infantile T-cell lymphopenia with or without nail dystrophy (TLIND) is an autosomal dominant disorder characterized by decreased numbers of T cells, particularly cytotoxic CD8+ T cells, usually apparent from infancy. Patients are often identified through newborn screening with the finding of low levels of T-cell receptor excision circles (TRECs). Affected individuals tend to be more susceptible to recurrent infections, mainly respiratory viral infections. However, the severity is highly variable, and patients usually improve with age later in childhood and as adults, even if CD8+ T cells remain decreased compared to normal. Additional features may include a small thymic shadow, indicative of impaired thymic development, skin abnormalities, such as atopic dermatitis, and nail dystrophy. As rare patients may develop more serious infections, affected individuals should be monitored. Bone marrow transplantation is not curative (summary by Bosticardo et al., 2019). [from OMIM]

Peeling skin syndrome 6

Peeling skin syndrome-6 (PSS6) is characterized by generalized ichthyotic dry skin and bullous peeling lesions on the trunk and limbs at sites of minor trauma. There is residual hyperpigmentation in areas of healing, but no scarring. Skin symptoms are exacerbated by warmth and humidity; however, the disorder improves markedly with age (Bolling et al., 2018; Mohamad et al., 2018). For a discussion of genetic heterogeneity of peeling skin syndrome, see PSS1 (270300). [from OMIM]

Hyper-IgE recurrent infection syndrome 5, autosomal recessive

Hyper-IgE syndrome-5 with recurrent infections (HEIS5) is an autosomal recessive immunologic disorder characterized by onset of recurrent sinopulmonary and deep skin infections in early childhood. The infections are mostly caused by bacteria, including H. influenza and Staphylococcus aureus. Additional features include atopic dermatitis, impaired inflammatory responses during infection, increased serum IgE, and increased IL6 (147620) (summary by Spencer et al., 2019). For a discussion of genetic heterogeneity of hyper-IgE syndrome, see HIES1 (147060). [from OMIM]

Autoinflammatory disease, systemic, with vasculitis

Systemic autoinflammatory disease with vasculitis (SAIDV) is an autosomal dominant disorder that manifests soon after birth with features such as purpuric skin rash, fever, hepatosplenomegaly, and elevated C-reactive protein (CRP; 123260). Laboratory studies may show leukocytosis, thrombocytopenia, and autoantibodies. A subset of patients develop progressive liver involvement that may result in fibrosis. Other systemic features, such as periorbital edema, conjunctivitis, infections, abdominal pain, and arthralgia are usually observed. Mutations occur de novo. De Jesus et al. (2023) referred to this disorder as LAVLI (LYN kinase-associated vasculopathy and liver fibrosis). [from OMIM]
