Genes affected
PTDSS2 (HGNC:15463): (phosphatidylserine synthase 2) The protein encoded by this gene catalyzes the conversion of phosphatidylethanolamine to phosphatidylserine, a structural membrane phospholipid that functions in cell signaling, blood coagulation, and apoptosis. The encoded enzyme also has a high affinity for docosahexaenoic acid (DHA) and can use it to make DHA-containing phosphatidylserine. [provided by RefSeq, Jul 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.1289G>A (p.R430H) alteration is located in exon 11 (coding exon 11) of the PTDSS2 gene. This alteration results from a G to A substitution at nucleotide position 1289, causing the arginine (R) at amino acid position 430 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
