Genes affected

XKRX (HGNC:29845): (XK related X-linked) This gene encodes a protein that is related to a component of the XK/Kell complex of the Kell blood group system. The encoded protein includes several transmembrane domains, is known to be exposed to the cell surface, and may function as a membrane transporter. [provided by RefSeq, May 2010]

The c.171C>G (p.I57M) alteration is located in exon 1 (coding exon 1) of the XKRX gene. This alteration results from a C to G substitution at nucleotide position 171, causing the isoleucine (I) at amino acid position 57 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
