Ambry Genetics

Jan 05, 2022

The c.535G>A (p.V179M) alteration is located in exon 1 (coding exon 1) of the C1GALT1C1L gene. This alteration results from a G to A substitution at nucleotide position 535, causing the valine (V) at amino acid position 179 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
