C9ORF57
Chr 9chromosome 9 open reading frame 57
The C9ORF57 protein is predicted to be located in cellular membranes, though its specific function remains unclear. Mutations in this gene cause autosomal recessive developmental and epileptic encephalopathy with microcephaly. The gene shows minimal constraint against loss-of-function variants, which is consistent with the recessive inheritance pattern observed in affected individuals.
