The c.301T>G (p.L101V) alteration is located in exon 1 (coding exon 1) of the GALNT15 gene. This alteration results from a T to G substitution at nucleotide position 301, causing the leucine (L) at amino acid position 101 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
