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.647A>G (p.N216S) alteration is located in exon 3 (coding exon 2) of the GIMAP8 gene. This alteration results from a A to G substitution at nucleotide position 647, causing the asparagine (N) at amino acid position 216 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
