Genes affected

TBCK (HGNC:28261): (TBC1 domain containing kinase) This gene encodes a protein that contains a protein kinase domain, a Rhodanase-like domain and the Tre-2/Bub2/Cdc16 (TBC) domain. The encoded protein is thought to play a role in actin organization, cell growth and cell proliferation by regulating the mammalian target of the rapamycin (mTOR) signaling pathway. This protein may also be involved in the transcriptional regulation of the components of the mTOR complex. Alternative splicing results in multiple transcript variants.

TBCK links:

AIMP1 (HGNC:10648): (aminoacyl tRNA synthetase complex interacting multifunctional protein 1) The protein encoded by this gene is a cytokine that is specifically induced by apoptosis, and it is involved in the control of angiogenesis, inflammation, and wound healing. The release of this cytokine renders the tumor-associated vasculature sensitive to tumor necrosis factor. The precursor protein is identical to the p43 subunit, which is associated with the multi-tRNA synthetase complex, and it modulates aminoacylation activity of tRNA synthetase in normal cells. This protein is also involved in the stimulation of inflammatory responses after proteolytic cleavage in tumor cells. Multiple transcript variants encoding different isoforms have been found for this gene. A pseudogene has been identified on chromosome 20. [provided by RefSeq, Dec 2008]

Variant summary: SCYE1 c.-26+204A>G alters a non-conserved nucleotide located in the untranslated mRNA region upstream of the initiation codon. It is also annotated as NM_001142416.1(AIMP1):c.1A>G (p.M1?) with the next in-frame alternative start codon located at p.25 in exon 2 of the coding sequence. 4/4 splicing computational tools predict no impact on splicing in either transcript. Furthermore, this gene has a pLI score that predicts tolerance to loss of function variation. The variant allele was found at a frequency of 3.7e-05 in 187564 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.-26+204A>G or c.1A>G in individuals affected with Hypomyelinating Leukodystrophy 3 and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
