Genes affected
PLSCR2 (HGNC:16494): (phospholipid scramblase 2) This gene encodes a member of the phospholipid scramblase family. Phospholipid scramblases are membrane proteins that mediate calcium-dependent, non-specific movement of plasma membrane phospholipids and phosphatidylserine exposure. The encoded protein contains a low affinity calcium binding motif and may play a role in blood coagulation and apoptosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.430C>T (p.R144W) alteration is located in exon 6 (coding exon 4) of the PLSCR2 gene. This alteration results from a C to T substitution at nucleotide position 430, causing the arginine (R) at amino acid position 144 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
