Genes affected

TRA2A (HGNC:16645): (transformer 2 alpha homolog) This gene is a member of the transformer 2 homolog family and encodes a protein with several RRM (RNA recognition motif) domains. This phosphorylated nuclear protein binds to specific RNA sequences and plays a role in the regulation of pre-mRNA splicing. Alternatively spliced transcript variants have been found for this gene.

The c.673G>A (p.G225S) alteration is located in exon 6 (coding exon 6) of the TRA2A gene. This alteration results from a G to A substitution at nucleotide position 673, causing the glycine (G) at amino acid position 225 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
