Collection Method: clinical testing

The c.305T>C (p.M102T) alteration is located in exon 1 (coding exon 1) of the TRIM49B gene. This alteration results from a T to C substitution at nucleotide position 305, causing the methionine (M) at amino acid position 102 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
