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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2024The c.1738C>G (p.H580D) alteration is located in exon 14 (coding exon 13) of the PPEF2 gene. This alteration results from a C to G substitution at nucleotide position 1738, causing the histidine (H) at amino acid position 580 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
