Ambry Genetics

Dec 20, 2023

The c.2429G>T (p.R810L) alteration is located in exon 16 (coding exon 15) of the FSTL4 gene. This alteration results from a G to T substitution at nucleotide position 2429, causing the arginine (R) at amino acid position 810 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
