Ambry Genetics

Apr 27, 2023

The c.1243A>G (p.M415V) alteration is located in exon 10 (coding exon 9) of the SNRNP70 gene. This alteration results from a A to G substitution at nucleotide position 1243, causing the methionine (M) at amino acid position 415 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
