Genes affected

GIMAP6 (HGNC:21918): (GTPase, IMAP family member 6) This gene encodes a member of the GTPases of immunity-associated proteins (GIMAP) family. GIMAP proteins contain GTP-binding and coiled-coil motifs, and may play roles in the regulation of cell survival. Decreased expression of this gene may play a role in non-small cell lung cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, which is found in a cluster with seven additional GIMAP genes on the long arm of chromosome 7.

The c.854G>A (p.C285Y) alteration is located in exon 3 (coding exon 2) of the GIMAP6 gene. This alteration results from a G to A substitution at nucleotide position 854, causing the cysteine (C) at amino acid position 285 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
