The c.770G>T (p.R257L) alteration is located in exon 8 (coding exon 8) of the CNOT6L gene. This alteration results from a G to T substitution at nucleotide position 770, causing the arginine (R) at amino acid position 257 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
