Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.46A>G (p.N16D) alteration is located in exon 3 (coding exon 1) of the BEX1 gene. This alteration results from a A to G substitution at nucleotide position 46, causing the asparagine (N) at amino acid position 16 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
