Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2 BP4

The NM_001353812.2(ATP11C):​c.2905G>C​(p.Val969Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V969M) has been classified as Benign.

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]

ATP11C Gene-Disease associations (from GenCC):

• X-linked congenital hemolytic anemia

  Inheritance: XL, Unknown Classification: LIMITED Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.36618334).
