Ambry Genetics

Oct 20, 2021

The c.276A>C (p.L92F) alteration is located in exon 6 (coding exon 5) of the FAM3C gene. This alteration results from a A to C substitution at nucleotide position 276, causing the leucine (L) at amino acid position 92 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
