Genes affected

DHODH (HGNC:2867): (dihydroorotate dehydrogenase (quinone)) The protein encoded by this gene catalyzes the fourth enzymatic step, the ubiquinone-mediated oxidation of dihydroorotate to orotate, in de novo pyrimidine biosynthesis. This protein is a mitochondrial protein located on the outer surface of the inner mitochondrial membrane. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 9: BayesDel_addAF, BayesDel_noAF, Cadd, Eigen, M_CAP, MutationAssessor, PROVEAN, REVEL, REVEL [when Dann, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster, phyloP100way_vertebrate was below the threshold]

PP5

Variant 16-72014641-C-T is Pathogenic according to our data. Variant chr16-72014641-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 16801.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.2148906). . Strength limited to SUPPORTING due to the PP5.
