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.1192C>T (p.H398Y) alteration is located in exon 8 (coding exon 7) of the PCED1A gene. This alteration results from a C to T substitution at nucleotide position 1192, causing the histidine (H) at amino acid position 398 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
