Ambry Genetics

Dec 02, 2022

The c.862A>G (p.I288V) alteration is located in exon 7 (coding exon 7) of the FBLN7 gene. This alteration results from a A to G substitution at nucleotide position 862, causing the isoleucine (I) at amino acid position 288 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
