Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 07, 2024 | The c.823A>G (p.I275V) alteration is located in exon 5 (coding exon 5) of the MDH1B gene. This alteration results from a A to G substitution at nucleotide position 823, causing the isoleucine (I) at amino acid position 275 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
