Ambry Genetics

Apr 24, 2023

The c.719A>G (p.D240G) alteration is located in exon 7 (coding exon 7) of the RBFA gene. This alteration results from a A to G substitution at nucleotide position 719, causing the aspartic acid (D) at amino acid position 240 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
