Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_001370597.1(ATP8B2):ā€‹c.932C>Gā€‹(p.Pro311Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000506 in 1,614,132 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P311L) has been classified as Uncertain significance.

Genes affected
ATP8B2 (HGNC:13534): (ATPase phospholipid transporting 8B2) The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of aminophospholipid-transporting ATPases. The aminophospholipid translocases transport phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.1031C>G (p.P344R) alteration is located in exon 12 (coding exon 12) of the ATP8B2 gene. This alteration results from a C to G substitution at nucleotide position 1031, causing the proline (P) at amino acid position 344 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
