The c.207T>A (p.D69E) alteration is located in exon 2 (coding exon 2) of the GALNT16 gene. This alteration results from a T to A substitution at nucleotide position 207, causing the aspartic acid (D) at amino acid position 69 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
