Genes affected

ATP11C (HGNC:13554): (ATPase phospholipid transporting 11C) Enables phosphatidylethanolamine flippase activity and phosphatidylserine flippase activity. Predicted to be involved in phospholipid translocation; positive regulation of B cell differentiation; and pre-B cell differentiation. Located in endoplasmic reticulum and plasma membrane. Is integral component of plasma membrane. Implicated in X-linked congenital hemolytic anemia. [provided by Alliance of Genome Resources, Apr 2022]

The c.2594A>T (p.H865L) alteration is located in exon 22 (coding exon 22) of the ATP11C gene. This alteration results from a A to T substitution at nucleotide position 2594, causing the histidine (H) at amino acid position 865 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
