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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.629G>A (p.R210H) alteration is located in exon 9 (coding exon 9) of the ATP8B2 gene. This alteration results from a G to A substitution at nucleotide position 629, causing the arginine (R) at amino acid position 210 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
