Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2024The c.427G>A (p.G143S) alteration is located in exon 2 (coding exon 1) of the B3GNT9 gene. This alteration results from a G to A substitution at nucleotide position 427, causing the glycine (G) at amino acid position 143 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
