Variant 15-49876447-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong

The NM_024837.4(ATP8B4):c.2858G>A(p.Arg953His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000121 in 1,614,134 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/21 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. R953S) has been classified as Uncertain significance.

Genes affected

ATP8B4 (HGNC:13536): (ATPase phospholipid transporting 8B4 (putative)) This gene encodes a member of the cation transport ATPase (P-type) family and type IV subfamily. The encoded protein is involved in phospholipid transport in the cell membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]

Ambry Genetics

Dec 28, 2023

The c.2858G>A (p.R953H) alteration is located in exon 25 (coding exon 24) of the ATP8B4 gene. This alteration results from a G to A substitution at nucleotide position 2858, causing the arginine (R) at amino acid position 953 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
