The c.1334T>C (p.M445T) alteration is located in exon 11 (coding exon 11) of the CNOT6L gene. This alteration results from a T to C substitution at nucleotide position 1334, causing the methionine (M) at amino acid position 445 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
