Kenny-Caffey syndrome

What it is

A rare primary bone dysplasia syndrome characterized by growth retardation with proportionate short stature, cortical thickening and medullary stenosis of the long bones, delayed anterior fontanelle closure, hypocalcemia due to congenital hypoparathyroidism and facial dysmorphism, including prominent forehead, microphthalmia, and micrognathia. Additional manifestations include ocular and dental anomalies (e.g. corneal opacity, hyperopia, optic atrophy, tortuous retinal vessels, dental caries, enamel defects) and, occasionally, hypoplastic nails and neonatal liver disease. Inheritance may be autosomal dominant or autosomal recessive, with more severe growth retardation, small hands and feet, intellectual disability, microcephaly and recurrent bacterial infections being observed in the latter.

Malformation syndrome

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Genes reported in subtypes

Orphanet records these genes on 2 more specific entries under this disorder, not on this entry itself:

A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
