The c.1668T>G (p.I556M) alteration is located in exon 16 (coding exon 16) of the TLE1 gene. This alteration results from a T to G substitution at nucleotide position 1668, causing the isoleucine (I) at amino acid position 556 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
