Ambry Genetics

Apr 24, 2023

The c.2347G>C (p.A783P) alteration is located in exon 21 (coding exon 21) of the FRMD4B gene. This alteration results from a G to C substitution at nucleotide position 2347, causing the alanine (A) at amino acid position 783 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
