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.134A>G (p.H45R) alteration is located in exon 2 (coding exon 2) of the TRA2A gene. This alteration results from a A to G substitution at nucleotide position 134, causing the histidine (H) at amino acid position 45 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
