Genes affected

PPEF1 (HGNC:9243): (protein phosphatase with EF-hand domain 1) 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 has been suggested to play a role in specific sensory neuron function and/or development. This gene shares high sequence similarity with the Drosophila retinal degeneration C (rdgC) gene. Several alternatively spliced transcript variants, each encoding a distinct isoform, have been described. [provided by RefSeq, Jul 2008]

The c.410A>G (p.H137R) alteration is located in exon 8 (coding exon 5) of the PPEF1 gene. This alteration results from a A to G substitution at nucleotide position 410, causing the histidine (H) at amino acid position 137 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
