Genes affected

C12orf4 (HGNC:1184): (FERRY endosomal RAB5 effector complex subunit 3) This gene is highly conserved from nematodes to humans. In rat, the orthologous gene encodes a cytoplasmic protein that is involved in mast cell degranulation. The human gene has been implicated in autosomal recessive intellectual disability.
