The c.1195A>G (p.R399G) alteration is located in exon 11 (coding exon 11) of the SCAF8 gene. This alteration results from a A to G substitution at nucleotide position 1195, causing the arginine (R) at amino acid position 399 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
