Genes affected

GIMAP5 (HGNC:18005): (GTPase, IMAP family member 5) 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. This gene encodes an antiapoptotic protein that functions in T-cell survival. Polymorphisms in this gene are associated with systemic lupus erythematosus. Read-through transcription exists between this gene and the neighboring upstream GIMAP1 (GTPase, IMAP family member 1) gene. [provided by RefSeq, Dec 2010]

GIMAP1-GIMAP5 (HGNC:51257): (GIMAP1-GIMAP5 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring GIMAP1 (GTPase, IMAP family member 1) and GIMAP5 (GTPase, IMAP family member 5) genes on chromosome 7. Alternative splicing results in multiple readthrough transcript variants, one of which encodes a fusion protein that shares sequence identity with each individual gene product.

GIMAP5 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.333 is higher than 0.05.
