Variant 22-31619640-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001326411.2(PISD):c.1202G>A(p.Arg401His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000273 in 1,614,134 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R401C) has been classified as Uncertain significance.

Genes affected

PISD (HGNC:8999): (phosphatidylserine decarboxylase) The protein encoded by this gene catalyzes the conversion of phosphatidylserine to phosphatidylethanolamine in the inner mitochondrial membrane. The encoded protein is active in phospholipid metabolism and interorganelle trafficking of phosphatidylserine. [provided by RefSeq, May 2016]

Apr 23, 2024

The c.1100G>A (p.R367H) alteration is located in exon 9 (coding exon 7) of the PISD gene. This alteration results from a G to A substitution at nucleotide position 1100, causing the arginine (R) at amino acid position 367 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
