Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2023The c.8G>A (p.R3Q) alteration is located in exon 2 (coding exon 1) of the BDH2 gene. This alteration results from a G to A substitution at nucleotide position 8, causing the arginine (R) at amino acid position 3 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
