Hyaline fibromatosis syndrome

What it is

A rare genetic disease characterized by infantile or childhood onset of abnormal growth of hyalinized fibrous tissue, giving rise to multiple cutaneous nodules and/or pearly papules predominantly affecting the scalp, ears, neck, face, hands, and feet. Involvement of other organs results in gingival hyperplasia, osteolytic bone lesions, and joint contractures. Some patients exhibit visceral involvement with intractable diarrhea, protein-losing enteropathy, increased susceptibility to infections, and severe failure to thrive.

Disease

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 this gene 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.
