Genes affected

GIMAP4 (HGNC:21872): (GTPase, IMAP family member 4) This gene encodes a protein belonging to the GTP-binding superfamily and to the immuno-associated nucleotide (IAN) subfamily of nucleotide-binding proteins. The encoded protein of this gene may be negatively regulated by T-cell acute lymphocytic leukemia 1 (TAL1). In humans, the IAN subfamily genes are located in a cluster at 7q36.1.

The c.763A>G (p.I255V) alteration is located in exon 3 (coding exon 2) of the GIMAP4 gene. This alteration results from a A to G substitution at nucleotide position 763, causing the isoleucine (I) at amino acid position 255 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
