Genes affected

PAFAH1B2 (HGNC:8575): (platelet activating factor acetylhydrolase 1b catalytic subunit 2) Platelet-activating factor acetylhydrolase (PAFAH) inactivates platelet-activating factor (PAF) into acetate and LYSO-PAF. This gene encodes the beta subunit of PAFAH, the other subunits are alpha and gamma. Multiple alternatively spliced transcript variants have been described for this gene.

The c.545C>T (p.S182L) alteration is located in exon 6 (coding exon 5) of the PAFAH1B2 gene. This alteration results from a C to T substitution at nucleotide position 545, causing the serine (S) at amino acid position 182 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
