Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.1134C>A (p.D378E) alteration is located in exon 6 (coding exon 6) of the A1BG gene. This alteration results from a C to A substitution at nucleotide position 1134, causing the aspartic acid (D) at amino acid position 378 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
