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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2024The c.874G>A (p.G292S) alteration is located in exon 3 (coding exon 3) of the XKRX gene. This alteration results from a G to A substitution at nucleotide position 874, causing the glycine (G) at amino acid position 292 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
