Collection Method: clinical testing

The c.1207A>G (p.R403G) alteration is located in exon 7 (coding exon 5) of the SNRK gene. This alteration results from a A to G substitution at nucleotide position 1207, causing the arginine (R) at amino acid position 403 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
