The c.681C>G (p.D227E) alteration is located in exon 1 (coding exon 1) of the KCTD12 gene. This alteration results from a C to G substitution at nucleotide position 681, causing the aspartic acid (D) at amino acid position 227 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
