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]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ATP9A. . Gene score misZ 4.1543 (greater than the threshold 3.09). Trascript score misZ 4.4901 (greater than threshold 3.09). GenCC has associacion of gene with neurodevelopmental disorder with poor growth and behavioral abnormalities.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.964
