Collection Method: clinical testing

The c.275C>T (p.T92M) alteration is located in exon 2 (coding exon 2) of the DHX15 gene. This alteration results from a C to T substitution at nucleotide position 275, causing the threonine (T) at amino acid position 92 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
