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]

The c.400T>C (p.Y134H) alteration is located in exon 5 (coding exon 5) of the ATP8B2 gene. This alteration results from a T to C substitution at nucleotide position 400, causing the tyrosine (Y) at amino acid position 134 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
