Ambry Genetics

Dec 14, 2023

The c.127G>T (p.A43S) alteration is located in exon 1 (coding exon 1) of the GALNT16 gene. This alteration results from a G to T substitution at nucleotide position 127, causing the alanine (A) at amino acid position 43 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
