Ambry Genetics

Jul 15, 2021

The c.1507G>A (p.E503K) alteration is located in exon 7 (coding exon 6) of the C14orf93 gene. This alteration results from a G to A substitution at nucleotide position 1507, causing the glutamic acid (E) at amino acid position 503 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
