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]

Ambry Genetics

Dec 18, 2023

The c.507C>A (p.N169K) alteration is located in exon 2 (coding exon 1) of the GIMAP8 gene. This alteration results from a C to A substitution at nucleotide position 507, causing the asparagine (N) at amino acid position 169 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
