Genes affected

ATP8B3 (HGNC:13535): (ATPase phospholipid transporting 8B3) 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 the other. This gene encodes member 3 of phospholipid-transporting ATPase 8B; other members of this protein family are located on chromosomes 1, 15 and 18. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

The c.3506T>C (p.V1169A) alteration is located in exon 27 (coding exon 26) of the ATP8B3 gene. This alteration results from a T to C substitution at nucleotide position 3506, causing the valine (V) at amino acid position 1169 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
