The c.337C>G (p.R113G) alteration is located in exon 3 (coding exon 3) of the SPATA33 gene. This alteration results from a C to G substitution at nucleotide position 337, causing the arginine (R) at amino acid position 113 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
