Ambry Genetics

Dec 01, 2022

The c.94C>G (p.L32V) alteration is located in exon 1 (coding exon 1) of the OLIG1 gene. This alteration results from a C to G substitution at nucleotide position 94, causing the leucine (L) at amino acid position 32 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
