Ambry Genetics

Nov 08, 2022

The c.406G>A (p.V136I) alteration is located in exon 4 (coding exon 4) of the DYNC1LI2 gene. This alteration results from a G to A substitution at nucleotide position 406, causing the valine (V) at amino acid position 136 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
