Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2024The c.439G>C (p.G147R) alteration is located in exon 2 (coding exon 1) of the B3GNT9 gene. This alteration results from a G to C substitution at nucleotide position 439, causing the glycine (G) at amino acid position 147 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
