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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2024The c.242G>A (p.R81H) alteration is located in exon 2 (coding exon 1) of the GIMAP8 gene. This alteration results from a G to A substitution at nucleotide position 242, causing the arginine (R) at amino acid position 81 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
