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.3760T>C (p.F1254L) alteration is located in exon 29 (coding exon 28) of the ATP8B3 gene. This alteration results from a T to C substitution at nucleotide position 3760, causing the phenylalanine (F) at amino acid position 1254 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
