The c.833G>C (p.S278T) alteration is located in exon 7 (coding exon 6) of the CDC37L1 gene. This alteration results from a G to C substitution at nucleotide position 833, causing the serine (S) at amino acid position 278 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
