Collection Method: clinical testing

The c.2497C>T (p.H833Y) alteration is located in exon 7 (coding exon 7) of the CCDC110 gene. This alteration results from a C to T substitution at nucleotide position 2497, causing the histidine (H) at amino acid position 833 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
