Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 29, 2024The c.253G>C (p.V85L) alteration is located in exon 5 (coding exon 4) of the BDH2 gene. This alteration results from a G to C substitution at nucleotide position 253, causing the valine (V) at amino acid position 85 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
