Genes affected

EPB41 (HGNC:3377): (erythrocyte membrane protein band 4.1) The protein encoded by this gene, together with spectrin and actin, constitute the red cell membrane cytoskeletal network. This complex plays a critical role in erythrocyte shape and deformability. Mutations in this gene are associated with type 1 elliptocytosis (EL1). Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Oct 2009]

The EPB41 c.487A>G; p.Arg163Gly variant (rs775969811), also known as c.-141A>G for NM_004437.4, to our knowledge, is not reported in the medical literature or gene specific databases. This variant is only observed on one allele in the Genome Aggregation Database (v2.1.1), indicating it is not a common polymorphism. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.22). Due to limited information, the clinical significance of this variant is uncertain at this time. -
