Genes affected

ATP10A (HGNC:13542): (ATPase phospholipid transporting 10A (putative)) The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of aminophospholipid-transporting ATPases. The aminophospholipid translocases transport phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. This gene is maternally expressed. It maps within the most common interval of deletion responsible for Angelman syndrome, also known as 'happy puppet syndrome'. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.84

Ambry Genetics

Jul 12, 2023

The c.3772C>G (p.P1258A) alteration is located in exon 20 (coding exon 20) of the ATP10A gene. This alteration results from a C to G substitution at nucleotide position 3772, causing the proline (P) at amino acid position 1258 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
