Genes affected

TMIGD3 (HGNC:51375): (transmembrane and immunoglobulin domain containing 3) This gene encodes a transmembrane and immunoglobulin domain-containing protein. Alternative splicing results in multiple transcript variants, one of which shares its 5' terminal exon with that of the overlapping adenosine A3 receptor gene (GeneID:140), thus resulting in a fusion product.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07013193).

The c.451A>G (p.I151V) alteration is located in exon 2 (coding exon 2) of the ADORA3 gene. This alteration results from a A to G substitution at nucleotide position 451, causing the isoleucine (I) at amino acid position 151 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
