Genes affected

EPB41L1 (HGNC:3378): (erythrocyte membrane protein band 4.1 like 1) Erythrocyte membrane protein band 4.1 (EPB41) is a multifunctional protein that mediates interactions between the erythrocyte cytoskeleton and the overlying plasma membrane. The encoded protein binds and stabilizes D2 and D3 dopamine receptors at the neuronal plasma membrane. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.68).
• BP7: Synonymous conserved (PhyloP=-2.48 with no splicing effect.
• BS2: High AC in GnomAdExome at 12 AD gene.
