Ambry Genetics

Feb 21, 2024

The c.1309G>A (p.V437I) alteration is located in exon 14 (coding exon 13) of the MEIOB gene. This alteration results from a G to A substitution at nucleotide position 1309, causing the valine (V) at amino acid position 437 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
