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 c.1952G>T (p.C651F) alteration is located in exon 12 (coding exon 12) of the EPB42 gene. This alteration results from a G to T substitution at nucleotide position 1952, causing the cysteine (C) at amino acid position 651 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
