RUSC2

Chr 9AR

RUN and SH3 domain containing 2

Also known as: Iporin, MRT61

NCBI Gene: 9853ENSG00000198853UniProt: Q8N2Y8OMIM: 611053

The protein associates with the adapter-like complex 4 (AP-4) and interacts with Rab1b and GM130, functioning in vesicular trafficking at the trans-Golgi network. Mutations cause autosomal recessive intellectual developmental disorder. This gene is highly constrained against loss-of-function variants (pLI 0.999, LOEUF 0.253).

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
