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]

Jan 23, 2024

The c.1014T>G (p.D338E) alteration is located in exon 3 (coding exon 3) of the XKRX gene. This alteration results from a T to G substitution at nucleotide position 1014, causing the aspartic acid (D) at amino acid position 338 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
