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 GeneticsMar 07, 2024The c.1313G>T (p.W438L) alteration is located in exon 11 (coding exon 10) of the PPEF2 gene. This alteration results from a G to T substitution at nucleotide position 1313, causing the tryptophan (W) at amino acid position 438 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
