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.

Collection Method: clinical testing

The c.110G>A (p.R37H) alteration is located in exon 2 (coding exon 2) of the TRA2A gene. This alteration results from a G to A substitution at nucleotide position 110, causing the arginine (R) at amino acid position 37 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
