Ambry Genetics

Sep 20, 2023

The c.2119G>A (p.V707I) alteration is located in exon 14 (coding exon 14) of the MCTP1 gene. This alteration results from a G to A substitution at nucleotide position 2119, causing the valine (V) at amino acid position 707 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
