The c.752C>T (p.T251M) alteration is located in exon 5 (coding exon 5) of the CCDC136 gene. This alteration results from a C to T substitution at nucleotide position 752, causing the threonine (T) at amino acid position 251 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
