Genes affected

TAOK1 (HGNC:29259): (TAO kinase 1) Enables alpha-tubulin binding activity; beta-tubulin binding activity; and kinase activity. Involved in several processes, including mitotic G2 DNA damage checkpoint signaling; negative regulation of microtubule depolymerization; and positive regulation of JNK cascade. Located in microtubule cytoskeleton and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a domain Protein kinase (size 253) in uniprot entity TAOK1_HUMAN there are 12 pathogenic changes around while only 0 benign (100%) in NM_020791.4
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, TAOK1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.95
• PP5: Variant 17-29477686-C-T is Pathogenic according to our data. Variant chr17-29477686-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 982831.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr17-29477686-C-T is described in Lovd as [Pathogenic].
