Collection Method: clinical testing

The c.782C>T (p.T261M) alteration is located in exon 7 (coding exon 6) of the SRRT gene. This alteration results from a C to T substitution at nucleotide position 782, causing the threonine (T) at amino acid position 261 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
