The c.341T>C (p.M114T) alteration is located in exon 5 (coding exon 3) of the CCDC77 gene. This alteration results from a T to C substitution at nucleotide position 341, causing the methionine (M) at amino acid position 114 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
