Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.314A>T (p.N105I) alteration is located in exon 5 (coding exon 4) of the BDH2 gene. This alteration results from a A to T substitution at nucleotide position 314, causing the asparagine (N) at amino acid position 105 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
