not specified Uncertain:1
The c.597C>G (p.H199Q) alteration is located in exon 3 (coding exon 2) of the B3GNT4 gene. This alteration results from a C to G substitution at nucleotide position 597, causing the histidine (H) at amino acid position 199 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
