Genes affected

ATP8A1 (HGNC:13531): (ATPase phospholipid transporting 8A1) The P-type adenosinetriphosphatases (P-type ATPases) are a family of proteins which use the free energy of ATP hydrolysis to drive uphill transport of ions across membranes. Several subfamilies of P-type ATPases have been identified. One subfamily catalyzes transport of heavy metal ions. Another subfamily transports non-heavy metal ions (NMHI). The protein encoded by this gene is a member of the third subfamily of P-type ATPases and acts to transport amphipaths, such as phosphatidylserine. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.3368G>A (p.R1123H) alteration is located in exon 36 (coding exon 36) of the ATP8A1 gene. This alteration results from a G to A substitution at nucleotide position 3368, causing the arginine (R) at amino acid position 1123 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
