Conditions with this feature

Aspartylglucosaminuria
MedGen UID:
78649
Concept ID:
C0268225
Disease or Syndrome
Aspartylglucosaminuria is a lysosomal storage disorder characterized by developmental delay, intellectual disability, behavioral manifestations (hyperactivity in young children, anxiety and restlessness in adolescence, and apathy in adulthood), recurrent infections, musculoskeletal features, and characteristic craniofacial features (prominent supraorbital ridges, hypertelorism, periorbital fullness, short nose with broad nasal bridge, thick vermilion of the upper and lower lips, and macroglossia) that become more prominent with age. Additional neurologic manifestations can include seizures, poor balance and coordination, and progressive cerebral atrophy in adulthood. Macrocephaly is common. Musculoskeletal features include lordosis, scoliosis, and arthritis in adolescents and young adults; vertebral dysplasia and/or rib cage abnormalities; and progressive muscle wasting, joint contractures, bursitis, and osteoporosis in adulthood. Skin manifestations (facial seborrhea, rosacea, and angiofibromas), gastrointestinal manifestations, neutropenia, and thrombocytopenia occur in some individuals. The clinical manifestations of aspartylglucosaminuria worsen with age, and adults have progressive psychomotor decline.
X-linked intellectual disability with marfanoid habitus
MedGen UID:
167096
Concept ID:
C0796022
Disease or Syndrome
MED12-related disorders include the phenotypes of FG syndrome type 1 (FGS1), Lujan syndrome (LS), X-linked Ohdo syndrome (XLOS), Hardikar syndrome (HS), and nonspecific intellectual disability (NSID). FGS1 and LS share the clinical findings of cognitive impairment, hypotonia, and abnormalities of the corpus callosum. FGS1 is further characterized by absolute or relative macrocephaly, tall forehead, downslanted palpebral fissures, small and simple ears, constipation and/or anal anomalies, broad thumbs and halluces, and characteristic behavior. LS is further characterized by large head, tall thin body habitus, long thin face, prominent nasal bridge, high narrow palate, and short philtrum. Carrier females in families with FGS1 and LS are typically unaffected. XLOS is characterized by intellectual disability, blepharophimosis, and facial coarsening. HS has been described in females with cleft lip and/or cleft palate, biliary and liver anomalies, intestinal malrotation, pigmentary retinopathy, and coarctation of the aorta. Developmental and cognitive concerns have not been reported in females with HS. Pathogenic variants in MED12 have been reported in an increasing number of males and females with NSID, with affected individuals often having clinical features identified in other MED12-related disorders.
Intellectual disability, X-linked 2
MedGen UID:
162922
Concept ID:
C0796207
Mental or Behavioral Dysfunction
Nonsyndromic mental retardation with a large head, relatively short stature, highly arched palate, square facies, short hands and feet, and macroorchidism.
Intellectual disability, X-linked 14
MedGen UID:
163231
Concept ID:
C0796220
Mental or Behavioral Dysfunction
Nonsyndromic mental retardation with inconsistent abnormalities.
X-linked intellectual disability-psychosis-macroorchidism syndrome
MedGen UID:
163232
Concept ID:
C0796222
Disease or Syndrome
The spectrum of MECP2-related phenotypes in females ranges from classic Rett syndrome to variant Rett syndrome with a broader clinical phenotype (either milder or more severe than classic Rett syndrome) to mild learning disabilities; the spectrum in males ranges from severe neonatal encephalopathy to pyramidal signs, parkinsonism, and macroorchidism (PPM-X) syndrome to severe syndromic/nonsyndromic intellectual disability. Females: Classic Rett syndrome, a progressive neurodevelopmental disorder primarily affecting girls, is characterized by apparently normal psychomotor development during the first six to 18 months of life, followed by a short period of developmental stagnation, then rapid regression in language and motor skills, followed by long-term stability. During the phase of rapid regression, repetitive, stereotypic hand movements replace purposeful hand use. Additional findings include fits of screaming and inconsolable crying, autistic features, panic-like attacks, bruxism, episodic apnea and/or hyperpnea, gait ataxia and apraxia, tremors, seizures, and acquired microcephaly. Males: Severe neonatal-onset encephalopathy, the most common phenotype in affected males, is characterized by a relentless clinical course that follows a metabolic-degenerative type of pattern, abnormal tone, involuntary movements, severe seizures, and breathing abnormalities. Death often occurs before age two years.
Syndromic X-linked intellectual disability Shashi type
MedGen UID:
335348
Concept ID:
C1846145
Disease or Syndrome
The Shashi type of X-linked syndromic intellectual developmental disorder (MRXSSH) is characterized by moderately impaired intellectual development and distinctive craniofacial skeletal structure and dysmorphism (Shashi et al., 2015).
Prolactin deficiency with obesity and enlarged testes
MedGen UID:
341515
Concept ID:
C1849698
Disease or Syndrome
17q11.2 microduplication syndrome
MedGen UID:
501218
Concept ID:
C3495679
Disease or Syndrome
Syndrome that has characteristics of dysmorphic features and intellectual deficit. It has been described in seven patients within one family. 17q11.2 microduplication encompasses the NF1 region. The underlying mechanism may be non-allelic homologous recombination. The study of pedigree suggests that this microduplication segregates within the family for at least two generations. Two patients displayed a normal clinical presentation, suggesting an autosomal dominant pattern of inheritance with incomplete penetrance.
X-linked intellectual disability-cardiomegaly-congestive heart failure syndrome
MedGen UID:
763827
Concept ID:
C3550913
Disease or Syndrome
X-linked intellectual disability-cardiomegaly-congestive heart failure syndrome is a rare X-linked syndromic intellectual disability disorder characterized by profound intellectual disability, global developmental delay with absent speech, seizures, large joint contractures, abnormal position of thumbs and middle-age onset of cardiomegaly and atrioventricular valve abnormalities, resulting in subsequent congestive heart failure. Additional features include variable facial dysmorphism (notably large ears with overfolded helix) and large testes.
Intellectual developmental disorder with autism and macrocephaly
MedGen UID:
767287
Concept ID:
C3554373
Disease or Syndrome
CHD8-related neurodevelopmental disorder with overgrowth (CHD8-NDD) is characterized by generalized overgrowth, developmental delay / intellectual disability (DD/ID), autism spectrum disorder (ASD), neuropsychiatric issues, neurologic problems, sleep disturbance, and gastrointestinal issues The most common findings are the development of macrocephaly (most often during infancy) and tall stature (most typically during puberty), which is often accompanied by ASD and/or DD/ID. Most, if not all, affected individuals have some degree of DD, most commonly speech and motor delays. When present, ID is most often in the mild-to-moderate range. Sleep disturbance is characterized by difficulty with both initiation (delayed sleep onset) and maintenance (frequent night awakenings) of sleep. The most common gastrointestinal issue is constipation with or without periods of diarrhea. Less common features are hypotonia (about 30% of affected individuals), seizures (10%-15%), dystonia (rare), and Chiari I malformation (rare).
Intellectual disability, X-linked 21
MedGen UID:
1790509
Concept ID:
C5551510
Disease or Syndrome
NR0B1-related adrenal hypoplasia congenita includes both X-linked adrenal hypoplasia congenita (X-linked AHC) and Xp21 deletion (previously called complex glycerol kinase deficiency). X-linked AHC is characterized by primary adrenal insufficiency and/or hypogonadotropic hypogonadism (HH). Adrenal insufficiency is acute infantile onset (average age 3 weeks) in approximately 60% of affected males and childhood onset (ages 1-9 years) in approximately 40%. HH typically manifests in a male with adrenal insufficiency as delayed puberty (i.e., onset age >14 years) and less commonly as arrested puberty at about Tanner Stage 3. Rarely, X-linked AHC manifests initially in early adulthood as delayed-onset adrenal insufficiency, partial HH, and/or infertility. Heterozygous females very occasionally have manifestations of adrenal insufficiency or hypogonadotropic hypogonadism. Xp21 deletion includes deletion of NR0B1 (causing X-linked AHC) and GK (causing glycerol kinase deficiency), and in some cases deletion of DMD (causing Duchenne muscular dystrophy). Developmental delay has been reported in males with Xp21 deletion when the deletion extends proximally to include DMD or when larger deletions extend distally to include IL1RAPL1 and DMD.
Tessadori-Van Haaften neurodevelopmental syndrome 3
MedGen UID:
1824083
Concept ID:
C5774310
Disease or Syndrome
Tessadori-Bicknell-van Haaften neurodevelopmental syndrome-3 (TEBIVANED3) is characterized by global developmental delay with poor overall growth, impaired intellectual development, and speech difficulties. More variable features include hypotonia, microcephaly, and dysmorphic facies. The severity and manifestations of the disorder are highly variable (Tessadori et al., 2022). For a discussion of genetic heterogeneity of Tessadori-Bicknell-van Haaften neurodevelopmental disorder, see TEBIVANED1 (619758).
