Stickler syndrome type 1

Stickler syndrome is a connective tissue disorder that can include ocular findings of myopia, cataract, and retinal detachment; hearing loss that is both conductive and sensorineural; midfacial underdevelopment and cleft palate (either alone or as part of the Robin sequence); and mild spondyloepiphyseal dysplasia and/or precocious arthritis. Variable phenotypic expression of Stickler syndrome occurs both within and among families; interfamilial variability is in part explained by locus and allelic heterogeneity. [from GeneReviews]

Marshall syndrome

Marshall syndrome (MRSHS) is characterized by midfacial hypoplasia, cleft palate, ocular anomalies including high myopia and cataracts, sensorineural hearing loss, short stature with spondyloepiphyseal dysplasia, and arthropathy. In contrast to Stickler syndrome type II, it has less severe eye findings but striking ocular hypertelorism, more pronounced maxillary hypoplasia, and ectodermal abnormalities (summary by Shanske et al., 1997 and Ala-Kokko and Shanske, 2009). [from OMIM]

Stickler syndrome, type 4

Stickler syndrome is a connective tissue disorder that can include ocular findings of myopia, cataract, and retinal detachment; hearing loss that is both conductive and sensorineural; midfacial underdevelopment and cleft palate (either alone or as part of the Robin sequence); and mild spondyloepiphyseal dysplasia and/or precocious arthritis.

Roifman syndrome

Roifman syndrome is a multisystem disorder characterized by growth retardation, spondyloepiphyseal dysplasia, retinal dystrophy, distinctive facial dysmorphism, and immunodeficiency (summary by de Vries et al., 2006). [from OMIM]

Meier-Gorlin syndrome 5

Most people with Meier-Gorlin syndrome have distinctive facial features. In addition to being abnormally small, the ears may be low-set or rotated backward. Additional features can include a small mouth (microstomia), an underdeveloped lower jaw (micrognathia), full lips, and a narrow nose with a high nasal bridge.

Additional features of Meier-Gorlin syndrome can include difficulty feeding and a lung condition known as pulmonary emphysema or other breathing problems.

Abnormalities in sexual development may also occur in Meier-Gorlin syndrome. In some males with this condition, the testes are small or undescended (cryptorchidism). Affected females may have unusually small external genital folds (hypoplasia of the labia majora) and small breasts. Both males and females with this condition can have sparse or absent underarm (axillary) hair.

Meier-Gorlin syndrome is a condition primarily characterized by short stature. It is considered a form of primordial dwarfism because the growth problems begin before birth (intrauterine growth retardation). After birth, affected individuals continue to grow at a slow rate. Other characteristic features of this condition are underdeveloped or missing kneecaps (patellae), small ears, and, often, an abnormally small head (microcephaly). Despite a small head size, most people with Meier-Gorlin syndrome have normal intellect.

Some people with Meier-Gorlin syndrome have other skeletal abnormalities, such as unusually narrow long bones in the arms and legs, a deformity of the knee joint that allows the knee to bend backwards (genu recurvatum), and slowed mineralization of bones (delayed bone age). [from MedlinePlus Genetics]

Spondyloepimetaphyseal dysplasia, Isidor-Toutain type

The Isidor-Toutain type of spondyloepimetaphyseal dysplasia (SEMDIST) is characterized by normal birth length, early postnatal growth deficiency, severe short stature, and genu varum. Skeletal radiographs show platyspondyly and severe epiphyseal and metaphyseal changes in the lower limbs (Le Caignec et al., 2019). [from OMIM]

Richieri Costa-da Silva syndrome

A rare genetic myotonic syndrome characterised by childhood onset of progressive and severe myotonia (with generalised muscular hypertrophy and progressive impairment of gait) short stature, skeletal abnormalities (including pectus carinatum, short, wedge-shaped thoracolumbar vertebrae, kyphoscoliosis, genu valgum, irregular femoral epiphyses) and mild to moderate intellectual deficiency. Facial dysmorphism and joint limitation are not associated. There have been no further descriptions in the literature since 1984. [from SNOMEDCT_US]
