Oct 25, 2024

The c.97G>A (p.V33M) 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 97, causing the valine (V) at amino acid position 33 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
