Congenital idiopathic hypogonadotropic hypogonadism (IHH) is a disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. Idiopathic hypogonadotropic hypogonadism can be caused by an isolated defect in gonadotropin-releasing hormone (GNRH ) release, action, or both. Other associated nonreproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss, occur with variable frequency. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism has been called 'Kallmann syndrome (KS),' whereas in the presence of a normal sense of smell, it has been termed 'normosmic idiopathic hypogonadotropic hypogonadism (nIHH)' (summary by Raivio et al., 2007). Because families have been found to segregate both KS and nIHH, the disorder is here referred to as 'hypogonadotropic hypogonadism with or without anosmia (HH).'For a discussion of genetic heterogeneity of autosomal hypogonadotropic hypogonadism with or without anosmia, see {147950}.

Otospondylomegaepiphyseal dysplasia (OSMED) is characterized by sensorineural deafness and relatively short extremities with abnormally large knees and elbows but normal total body length. The diagnostic radiologic findings are the enlarged epiphyses combined with a moderate platyspondyly, most marked in the lower thoracic region. There are no ocular abnormalities. Patients have typical facial features, including midface hypoplasia (summary by Giedion et al., 1982). Some patients have osteoarthritis (Brunner et al., 1994).

Camptodactyly-tall stature-scoliosis-hearing loss syndrome is characterised by camptodactyly, tall stature, scoliosis, and hearing loss (CATSHL). It has been described in around 30 individuals from seven generations of the same family. The syndrome is caused by a missense mutation in the FGFR3 gene, leading to a partial loss of function of the encoded protein, which is a negative regulator of bone growth.

Stickler syndrome type 3 is a rare, genetic, multiple congenital anomalies/dysmorphic syndrome characterized by craniofacial dysmorphism (midface hypoplasia, depressed nasal bridge, small nose with upturned tip, cleft palate, Pierre Robin sequence), bilateral, pronounced sensorineural hearing loss, and skeletal/joint anomalies (including spondyloepiphyseal dysplasia, arthralgia/arthropathy), in the absence of ocular abnormalities.

Osteogenesis imperfecta type V is a moderate type of osteogenesis imperfecta (OI; see this term), a genetic disorder characterized by increased bone fragility, low bone mass and susceptibility to bone fractures with variable severity. OI type V is characterized by mild to moderate short stature, dislocation of the radial head, mineralized interosseous membranes, hyperplasic callus, white sclera and no dentinogenesis imperfecta (DI; see this term).

Corpus callosum agenesis-intellectual disability-coloboma-micrognathia syndrome is a developmental anomalies syndrome characterized by coloboma of the iris and optic nerve, facial dysmorphism (high forehead, microretrognathia, low-set ears), intellectual deficit, agenesis of the corpus callosum (ACC), sensorineural hearing loss, skeletal anomalies and short stature.

Waardenburg syndrome type 2 is an auditory-pigmentary syndrome characterized by pigmentary abnormalities of the hair, skin, and eyes; congenital sensorineural hearing loss; and the absence of 'dystopia canthorum,' the lateral displacement of the inner canthus of each eye, which is seen in some other forms of WS (review by Read and Newton, 1997). Individuals with WS type 2E, which is caused by mutation in the SOX10 gene (OMIM ), may have neurologic abnormalities, including mental impairment, myelination defects, and ataxia. Waardenburg syndrome type 2 is genetically heterogeneous (see WS2A; {193510}).For a description of other clinical variants of Waardenburg syndrome, see WS1 (OMIM ), WS3 (OMIM ), and WS4 (OMIM ).
