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:):

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.045625895).
• BP6: Variant 7-107563979-A-C is Benign according to our data. Variant chr7-107563979-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 1206117.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr7-107563979-A-C is described in Lovd as [Likely_benign].
