Ambry Genetics

Oct 24, 2023

The c.636C>G (p.I212M) 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 636, causing the isoleucine (I) at amino acid position 212 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
