      CaseAddInfo: Parents are non-consanguineous with unremarkable family history, Treatment with carnitine and restricted protein intake normalized symptoms, Sequencing of the mother revealed Variant 2 without Variant 1 confirming compound heterozygosity

      CasePreviousTesting: Metabolic acidosis values w/ elevated anion gap (pH = 6.96, bicarbonate 3.5 mmol/L and pCO2 15.9 mm Hg, anion gap 25.5 mmol/L); Mild hyperammonemia (107 μmol/L; ref. < 50); Elevated creatine kinase (from 498 IU/L initially up to 3062 IU/L, ref. < 150); Organic acid profiles were analyzed via gas chromatography–mass spectrometry with Table 1 showing relevant organic acid values; Proband was negative for propionyl-coA carboxylase deficency (811 pmol/min/mg protein with control mean 1123, PCCA and PCCB variants were negative) and ruled out MUT/cobalamin issues as well; Fusion experiments showed negative results for mut, cblA, and cblB complementation but no increase in activity when fused with MCEE confirming the pathway blockage

      CaseGenotypingMethod: Extracted DNA from blood was amplified and three coding exons/splice site junctions of MCEE were Sanger sequenced. A deletion/duplicaiton analysis yeilded normal results. To search for an intronic sequence variant, total RNA was extracted and reverse-transcribed to confirm a 92-bp insertion between Exons 2 and 3. Resulting sequencing of this genomic area revealed a deep intronic variant that created a new consensus donor splice site that leads to a premature stop codon.

      gnomAD: The maximum population minor allele frequency in gnomAD = 0.00002662 (European non-Finnish); no homozygotes in any population.

      VariantEvidence: The variant was expressed in S. cerevisae with a deletion of CargB, the year ortholog of OAT, that cannot grow in media with ornithine as the sole nitrogen source. Whereas expression of wild type OAT allows yeast to grow in media with ornithine as the sole nitrogen source, no growth was observed when the variant was expressed. OAT enzymatic activity was measured and was <10% normal, and OAT protein was barely detectable on Western blot.

      VariantEvidence: Expression of recombinant protein in bacteria revealed that the E97K are present in the insoluble fraction compared to wildtype which is found in the soluble. The little amount retained of each in the soluble fraction showed that they retained activity. Dehydratase activity of the patients duodenal mucosa cells showed reduced activity of he E97K (17% activity) mutant compared to wildtype , indicating that this mutation severely reduces the activity of PCBD1.

      CasePreviousTesting: Plasma amino acids and plasma acylcarnitine profile were normal. The organic acid in the urine showed an elevated 3‐hydroxyisovaleric acid (110 mmol/mol creatinine, normal <44 mmol/mol creatinine). Serum biotinidase activity was normal. Blood lactate and ammonia were normal in repeated measurements.

      CaseGenotypingMethod: Patient had the IVD exons and exon-intron boundaries analyzed using PCR/Sanger sequencing to follow up on suspected IVA, with no variants found. Whole Exome Sequencing was performed to determine the correct genetic cause of the disorder by evaluating all known exons and their flanking regions. This found two heterozygous missense mutations in HIBCH consistent with the diagnosis. Trio PCR/Sanger sequencing confirmed parental heterozygosity and the variants in the patient.
