The c.748C>T (p.R250W) alteration is located in exon 5 (coding exon 5) of the CCDC107 gene. This alteration results from a C to T substitution at nucleotide position 748, causing the arginine (R) at amino acid position 250 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
