Ambry Genetics

Nov 30, 2022

The c.590C>A (p.A197E) alteration is located in exon 5 (coding exon 5) of the FBLN7 gene. This alteration results from a C to A substitution at nucleotide position 590, causing the alanine (A) at amino acid position 197 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
