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.235A>G (p.T79A) 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 235, causing the threonine (T) at amino acid position 79 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
