Collection Method:clinical testing

The c.775C>T (p.R259C) alteration is located in exon 8 (coding exon 7) of the TSGA13 gene. This alteration results from a C to T substitution at nucleotide position 775, causing the arginine (R) at amino acid position 259 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
