Genes affected

EPB42 (HGNC:3381): (erythrocyte membrane protein band 4.2) Erythrocyte membrane protein band 4.2 is an ATP-binding protein which may regulate the association of protein 3 with ankyrin. It probably has a role in erythrocyte shape and mechanical property regulation. Mutations in the EPB42 gene are associated with recessive spherocytic elliptocytosis and recessively transmitted hereditary hemolytic anemia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The EPB42 c.424G>A variant is predicted to result in the amino acid substitution p.Ala142Thr. Homozygosity for p.Ala142Thr has been found most commonly in individuals of Japanese descent and was reported to lead to moderately severe hereditary spherocytosis. The p.Ala142Thr is a founder variant in the Japanese population with a carrier frequency of ~3% (Bouhassira et al 1992. PubMed ID: 1558976). This variant is reported in 0.060% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/15-43507389-C-T). This variant is interpreted as pathogenic. -
