The c.706C>G (p.R236G) alteration is located in exon 5 (coding exon 4) of the SUSD4 gene. This alteration results from a C to G substitution at nucleotide position 706, causing the arginine (R) at amino acid position 236 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
