Genes affected

DECR1 (HGNC:2753): (2,4-dienoyl-CoA reductase 1) Enables 2,4-dienoyl-CoA reductase (NADPH) activity; NADPH binding activity; and identical protein binding activity. Involved in fatty acid beta-oxidation. Located in cytosol; mitochondrion; and nucleoplasm. Part of catalytic complex. [provided by Alliance of Genome Resources, Apr 2022]

DECR1 Gene-Disease associations (from GenCC):

• liver disorder

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics
• progressive encephalopathy with leukodystrophy due to DECR deficiency

  Inheritance: Unknown Classification: LIMITED, NO_KNOWN Submitted by: ClinGen, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.62).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.184 is higher than 0.05.
