Genes affected

ULK2 (HGNC:13480): (unc-51 like autophagy activating kinase 2) This gene encodes a protein that is similar to a serine/threonine kinase in C. elegans which is involved in axonal elongation. The structure of this protein is similar to the C. elegans protein in that both proteins have an N-terminal kinase domain, a central proline/serine rich (PS) domain, and a C-terminal (C) domain. The gene is located within the Smith-Magenis syndrome region on chromosome 17. Alternatively spliced transcript variants encoding the same protein have been identified.

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-19797472-T-C is Pathogenic according to our data. Variant chr17-19797472-T-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 402174.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr17-19797472-T-C is described in Lovd as [Pathogenic].
• BP4: Computational evidence support a benign effect (MetaRNN=0.25570583).. Strength limited to SUPPORTING due to the PP5.
