PDRG1

Chr 20

p53 and DNA damage regulated 1

Also known as: C20orf126, PDRG

PDRG1 encodes a protein that binds unfolded proteins and is involved in chaperone-mediated protein folding as part of the RPAP3/R2TP/prefoldin-like complex. Mutations cause autosomal recessive developmental and epileptic encephalopathy with microcephaly. The gene is not highly constrained against loss-of-function variants.
