Genes affected
GIMAP2 (HGNC:21789): (GTPase, IMAP family member 2) 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2023The c.509A>G (p.K170R) alteration is located in exon 3 (coding exon 2) of the GIMAP2 gene. This alteration results from a A to G substitution at nucleotide position 509, causing the lysine (K) at amino acid position 170 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
