Ambry Genetics

Nov 15, 2021

The c.554G>C (p.G185A) alteration is located in exon 4 (coding exon 4) of the GUCA1C gene. This alteration results from a G to C substitution at nucleotide position 554, causing the glycine (G) at amino acid position 185 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
