Genes affected
ATP9A (HGNC:13540): (ATPase phospholipid transporting 9A (putative)) Enables protease binding activity. Involved in negative regulation of exosomal secretion; regulation of endocytic recycling; and regulation of retrograde transport, endosome to Golgi. Located in several cellular components, including endosome membrane; perinuclear region of cytoplasm; and trans-Golgi network membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.2158C>T (p.R720C) alteration is located in exon 20 (coding exon 20) of the ATP9A gene. This alteration results from a C to T substitution at nucleotide position 2158, causing the arginine (R) at amino acid position 720 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
