Genes affected

PPEF2 (HGNC:9244): (protein phosphatase with EF-hand domain 2) This gene encodes a member of the serine/threonine protein phosphatase with EF-hand motif family. The protein contains a protein phosphatase catalytic domain, and at least two EF-hand calcium-binding motifs in its C terminus. Although its substrate(s) is unknown, the encoded protein, which is expressed specifically in photoreceptors and the pineal, has been suggested to play a role in the visual system. This gene shares high sequence similarity with the Drosophila retinal degeneration C (rdgC) gene. [provided by RefSeq, Jul 2008]

The c.2164C>T (p.R722C) alteration is located in exon 17 (coding exon 16) of the PPEF2 gene. This alteration results from a C to T substitution at nucleotide position 2164, causing the arginine (R) at amino acid position 722 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
