Collection Method: clinical testing

The c.788T>C (p.M263T) alteration is located in exon 7 (coding exon 7) of the DEPDC1B gene. This alteration results from a T to C substitution at nucleotide position 788, causing the methionine (M) at amino acid position 263 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
