The c.504C>G (p.S168R) alteration is located in exon 3 (coding exon 3) of the SHD gene. This alteration results from a C to G substitution at nucleotide position 504, causing the serine (S) at amino acid position 168 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
