Targeted gene under study

RNF113A, OMIM#300953


RNF113A is known to be associated in related X-linked trichothiodystrophy. The 5 males affected described in literature presented with global developmental delay / severe intellectual disability, microcephaly, cerebellar hypoplasia and abnormal corpus callosum, sparse and brittle hair with dry skin, and endocrine features associated with genital abnormalities. Female carriers were described with a 100% skewed XCI profile and short stature only.

We report the first female presenting with a pathogenic variant in RNF113A a spectrum of symptomatic X-linked trichothiodystrophy.

We wish to identify further individuals (females or males) with RNF113A variants to better define the phenotypic spectrum.
