Genes affected
KEL (HGNC:6308): (Kell metallo-endopeptidase (Kell blood group)) This gene encodes a type II transmembrane glycoprotein that is the highly polymorphic Kell blood group antigen. The Kell glycoprotein links via a single disulfide bond to the XK membrane protein that carries the Kx antigen. The encoded protein contains sequence and structural similarity to members of the neprilysin (M13) family of zinc endopeptidases. [provided by RefSeq, Jul 2008]

The c.2141A>T (p.Y714F) alteration is located in exon 19 (coding exon 19) of the KEL gene. This alteration results from a A to T substitution at nucleotide position 2141, causing the tyrosine (Y) at amino acid position 714 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
