Ambry Genetics

Feb 14, 2024

The c.252G>T (p.M84I) alteration is located in exon 1 (coding exon 1) of the CNTLN gene. This alteration results from a G to T substitution at nucleotide position 252, causing the methionine (M) at amino acid position 84 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
