Genes affected

GIMAP8 (HGNC:21792): (GTPase, IMAP family member 8) This gene encodes a protein belonging to the GTP-binding superfamily and to the immuno-associated nucleotide (IAN) subfamily of nucleotide-binding proteins. In humans, the IAN subfamily genes are located in a cluster at 7q36.1. [provided by RefSeq, Jul 2008]

The c.718G>A (p.E240K) alteration is located in exon 4 (coding exon 3) of the GIMAP8 gene. This alteration results from a G to A substitution at nucleotide position 718, causing the glutamic acid (E) at amino acid position 240 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
