Ambry Genetics

Jul 12, 2023

The c.35T>C (p.L12P) alteration is located in exon 1 (coding exon 1) of the FBLN7 gene. This alteration results from a T to C substitution at nucleotide position 35, causing the leucine (L) at amino acid position 12 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
