Ambry Genetics

Jun 22, 2021

The c.514G>C (p.E172Q) alteration is located in exon 5 (coding exon 5) of the C1orf185 gene. This alteration results from a G to C substitution at nucleotide position 514, causing the glutamic acid (E) at amino acid position 172 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
