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.

The c.1772C>T (p.T591M) alteration is located in exon 15 (coding exon 14) of the EPB41L1 gene. This alteration results from a C to T substitution at nucleotide position 1772, causing the threonine (T) at amino acid position 591 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
