The c.961C>G (p.R321G) alteration is located in exon 3 (coding exon 3) of the MYCL gene. This alteration results from a C to G substitution at nucleotide position 961, causing the arginine (R) at amino acid position 321 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
