The c.674C>A (p.A225E) alteration is located in exon 8 (coding exon 7) of the TSGA13 gene. This alteration results from a C to A substitution at nucleotide position 674, causing the alanine (A) at amino acid position 225 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
