Genes affected

PCED1A (HGNC:16212): (PC-esterase domain containing 1A) The protein encoded by this gene is a member of the GDSL/SGNH superfamily. Members of this family are hydrolytic enzymes with esterase and lipase activity and broad substrate specificity. This protein belongs to the Pmr5-Cas1p-esterase subfamily in that it contains the catalytic triad comprised of serine, aspartate and histidine and lacks two conserved regions (glycine after strand S2 and GxND motif). A pseudogene of this gene has been identified on the long arm of chromosome 2. Alternative splicing results in multiple transcript variants that encode different protein isoforms.

The c.893A>G (p.H298R) alteration is located in exon 7 (coding exon 6) of the PCED1A gene. This alteration results from a A to G substitution at nucleotide position 893, causing the histidine (H) at amino acid position 298 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
