Genes affected

ACAD9 (HGNC:21497): (acyl-CoA dehydrogenase family member 9) This gene encodes a member of the acyl-CoA dehydrogenase family. Members of this family of proteins localize to the mitochondria and catalyze the rate-limiting step in the beta-oxidation of fatty acyl-CoA. The encoded protein is specifically active toward palmitoyl-CoA and long-chain unsaturated substrates. Mutations in this gene cause acyl-CoA dehydrogenase family member type 9 deficiency. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Mar 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.02150324).

BP6

Variant 3-128904091-A-C is Benign according to our data. Variant chr3-128904091-A-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 136254.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00143 (218/152344) while in subpopulation EAS AF = 0.028 (145/5184). AF 95% confidence interval is 0.0243. There are 9 homozygotes in GnomAd4. There are 103 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 9 AR gene
