Genes affected

DUS4L (HGNC:21517): (dihydrouridine synthase 4 like) Predicted to enable tRNA dihydrouridine synthase activity. Predicted to be involved in tRNA dihydrouridine synthesis. [provided by Alliance of Genome Resources, Apr 2022]

COG5 (HGNC:14857): (component of oligomeric golgi complex 5) The protein encoded by this gene is one of eight proteins (Cog1-8) which form a Golgi-localized complex (COG) required for normal Golgi morphology and function. The encoded protein is organized with conserved oligomeric Golgi complex components 6, 7 and 8 into a sub-complex referred to as lobe B. Alternative splicing results in multiple transcript variants. Mutations in this gene result in congenital disorder of glycosylation type 2I.[provided by RefSeq, Jan 2011]

DUS4L-BCAP29 (HGNC:54422): (DUS4L-BCAP29 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring DUS4L (dihydrouridine synthase 4 like) and BCAP29 (B cell receptor associated protein 29) genes on chromosome 7. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Jul 2019]

DUS4L (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.
