Genes affected

ILK (HGNC:6040): (integrin linked kinase) This gene encodes a protein with a kinase-like domain and four ankyrin-like repeats. The encoded protein associates at the cell membrane with the cytoplasmic domain of beta integrins, where it regulates integrin-mediated signal transduction. Activity of this protein is important in the epithelial to mesenchymal transition, and over-expression of this gene is implicated in tumor growth and metastasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013]

ILK links:

TAF10 (HGNC:11543): (TATA-box binding protein associated factor 10) Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. This gene encodes one of the small subunits of TFIID that is associated with a subset of TFIID complexes. Studies with human and mammalian cells have shown that this subunit is required for transcriptional activation by the estrogen receptor, for progression through the cell cycle, and may also be required for certain cellular differentiation programs.

The V49A variant has notbeen published as pathogenic or been reported as benign to our knowledge. In addition, it is notobserved at a significant frequency in large population cohorts (Lek et al., 2016; 1000 GenomesConsortium et al., 2015; Exome Variant Server). Although the V49A variant is a conservative aminoacid substitution, which is not likely to impact secondary protein structure as these residues sharesimilar properties, this substitution does occur at a position that is conserved across species. Moreover,in silico analysis predicts this variant is probably damaging to the protein structure/function.Nonetheless, this variant lacks observation in a significant number of affected individuals, segregationdata, and functional evidence, which would further clarify its pathogenicity. -

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 49 of the ILK protein (p.Val49Ala). This variant is present in population databases (rs201499797, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with ILK-related conditions. ClinVar contains an entry for this variant (Variation ID: 432620). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
