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 GeneticsDec 07, 2021The c.1313C>T (p.A438V) alteration is located in exon 14 (coding exon 14) of the ATP9A gene. This alteration results from a C to T substitution at nucleotide position 1313, causing the alanine (A) at amino acid position 438 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
