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]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 10, 2023In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with EPB41-related conditions. This variant is present in population databases (rs753385565, gnomAD 0.006%). This variant, c.518_520del, results in the deletion of 1 amino acid(s) of the EPB41 protein (p.Gly173del), but otherwise preserves the integrity of the reading frame. The EPB41 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_001166005.1, and corresponds to NM_004437.3:c.-110_-108del in the primary transcript. -
