Ambry Genetics

Feb 23, 2023

The c.457G>A (p.V153M) alteration is located in exon 2 (coding exon 1) of the OSR1 gene. This alteration results from a G to A substitution at nucleotide position 457, causing the valine (V) at amino acid position 153 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
