Ambry Genetics

Sep 01, 2021

The c.556G>C (p.A186P) alteration is located in exon 4 (coding exon 4) of the C8orf76 gene. This alteration results from a G to C substitution at nucleotide position 556, causing the alanine (A) at amino acid position 186 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
