Ambry Genetics

Nov 17, 2022

The c.3056T>C (p.I1019T) alteration is located in exon 25 (coding exon 25) of the OVCH1 gene. This alteration results from a T to C substitution at nucleotide position 3056, causing the isoleucine (I) at amino acid position 1019 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
