Ambry Genetics

Nov 02, 2021

The c.221C>A (p.P74Q) alteration is located in exon 2 (coding exon 2) of the FBLN7 gene. This alteration results from a C to A substitution at nucleotide position 221, causing the proline (P) at amino acid position 74 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
