The c.977G>A (p.R326Q) alteration is located in exon 11 (coding exon 11) of the B3GNTL1 gene. This alteration results from a G to A substitution at nucleotide position 977, causing the arginine (R) at amino acid position 326 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
