The c.836C>T (p.P279L) alteration is located in exon 7 (coding exon 7) of the FBLN7 gene. This alteration results from a C to T substitution at nucleotide position 836, causing the proline (P) at amino acid position 279 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
