- Abstract
In 2008, SLC29A3 has been implicated in a syndromic form of genodermatosis: H syndrome. The major features encountered in H syndrome are Hearing loss, Hyperglycaemia, Heart anomalies, Hypertrichosis, Hyperpigmentation, Hepatomegaly and Hypogonadism. More recently, SLC29A3 mutations have been described in families presenting syndromes associating generalized histiocytosis to systemic progressive features: severe camptodactyly, hearing loss, hypogonadism, hepatomegaly, heart defects and skin hyperpigmentation. We have identified a homozygous missense SLC29A3 mutation in a patient presenting with only a progressive sensorineural hearing impairment and a single cervical node (Rosai Dorfman). SLC29A3 mutations appear to be involved in a large phenotypic continuum which should prompt physicians to study this gene even in mild clinical presentations.
