not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 18, 2023 | The c.920A>G (p.D307G) alteration is located in exon 6 (coding exon 6) of the MDH1B gene. This alteration results from a A to G substitution at nucleotide position 920, causing the aspartic acid (D) at amino acid position 307 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
