Collection Method: clinical testing

The c.122C>G (p.A41G) alteration is located in exon 2 (coding exon 1) of the SRRM3 gene. This alteration results from a C to G substitution at nucleotide position 122, causing the alanine (A) at amino acid position 41 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
