Genes affected

PLSCR3 (HGNC:16495): (phospholipid scramblase 3) Enables several functions, including calcium-dependent protein binding activity; metal ion binding activity; and phospholipid scramblase activity. Involved in several processes, including cardiolipin biosynthetic process; regulation of apoptotic process; and regulation of release of cytochrome c from mitochondria. Located in cytosol; mitochondrion; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

PLSCR3 links:

TMEM256-PLSCR3 (HGNC:49186): (TMEM256-PLSCR3 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring chromosome 17 open reading frame 61 (C17orf61) and phospholipid scramblase 3 (PLSCR3) genes. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is unlikely to produce a protein product. [provided by RefSeq, Jan 2011]

Ambry Genetics

Aug 13, 2021

The c.55C>T (p.P19S) alteration is located in exon 3 (coding exon 2) of the PLSCR3 gene. This alteration results from a C to T substitution at nucleotide position 55, causing the proline (P) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
