Genes affected

OXCT1 (HGNC:8527): (3-oxoacid CoA-transferase 1) This gene encodes a member of the 3-oxoacid CoA-transferase gene family. The encoded protein is a homodimeric mitochondrial matrix enzyme that plays a central role in extrahepatic ketone body catabolism by catalyzing the reversible transfer of coenzyme A from succinyl-CoA to acetoacetate. Mutations in this gene are associated with succinyl CoA:3-oxoacid CoA transferase deficiency. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 5-41730384-T-C is Benign according to our data. Variant chr5-41730384-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 904184.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000243 (37/152370) while in subpopulation SAS AF = 0.00311 (15/4824). AF 95% confidence interval is 0.00192. There are 1 homozygotes in GnomAd4. There are 21 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
