Genes affected
PLSCR1 (HGNC:9092): (phospholipid scramblase 1) This gene encodes a phospholipid scramblase family member. The encoded protein is involved in disruption of the asymmetrical distribution of phospholipids between the inner and outer leaflets of the plasma membrane, resulting in externalization of phosphatidylserine. This cell membrane disruption plays an important role in the blood coagulation cascade as well as macrophage clearing of apoptotic cells. The encoded protein has additionally been implicated in gene regulation and interferon-induced antiviral responses. [provided by RefSeq, May 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 13, 2023The c.719G>T (p.C240F) alteration is located in exon 7 (coding exon 6) of the PLSCR1 gene. This alteration results from a G to T substitution at nucleotide position 719, causing the cysteine (C) at amino acid position 240 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
