Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2023The c.952G>A (p.G318S) alteration is located in exon 6 (coding exon 6) of the A1BG gene. This alteration results from a G to A substitution at nucleotide position 952, causing the glycine (G) at amino acid position 318 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
