Ambry Genetics

Jul 20, 2021

The c.299A>C (p.D100A) alteration is located in exon 3 (coding exon 1) of the RFPL4B gene. This alteration results from a A to C substitution at nucleotide position 299, causing the aspartic acid (D) at amino acid position 100 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
