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.

Ambry Genetics

Aug 02, 2021

The c.419T>C (p.M140T) alteration is located in exon 2 (coding exon 2) of the ADORA3 gene. This alteration results from a T to C substitution at nucleotide position 419, causing the methionine (M) at amino acid position 140 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
