Ambry Genetics

Nov 14, 2023

The c.876C>G (p.F292L) alteration is located in exon 4 (coding exon 4) of the ZNF20 gene. This alteration results from a C to G substitution at nucleotide position 876, causing the phenylalanine (F) at amino acid position 292 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
