Collection Method: clinical testing

The c.346T>C (p.Y116H) alteration is located in exon 4 (coding exon 4) of the CCDC60 gene. This alteration results from a T to C substitution at nucleotide position 346, causing the tyrosine (Y) at amino acid position 116 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
