Ambry Genetics

Nov 15, 2024

The c.122T>C (p.I41T) alteration is located in exon 4 (coding exon 2) of the CCDC122 gene. This alteration results from a T to C substitution at nucleotide position 122, causing the isoleucine (I) at amino acid position 41 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
