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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2022The c.529G>A (p.G177R) alteration is located in exon 6 (coding exon 5) of the PAFAH1B2 gene. This alteration results from a G to A substitution at nucleotide position 529, causing the glycine (G) at amino acid position 177 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
