Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2906G>C (p.S969T) alteration is located in exon 17 (coding exon 16) of the CCDC73 gene. This alteration results from a G to C substitution at nucleotide position 2906, causing the serine (S) at amino acid position 969 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
