Ambry Genetics

Feb 03, 2022

The c.745G>A (p.A249T) 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 745, causing the alanine (A) at amino acid position 249 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
