Genes affected

KIAA1549 (HGNC:22219): (KIAA1549) The protein encoded by this gene belongs to the UPF0606 family. This gene has been found to be fused to the BRAF oncogene in many cases of pilocytic astrocytoma. The fusion results from 2Mb tandem duplications at 7q34. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2012]

This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1939 of the KIAA1549 protein (p.Ser1939Ala). This variant is present in population databases (rs557851564, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with KIAA1549-related conditions. ClinVar contains an entry for this variant (Variation ID: 851361). 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 disruptive. 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. -
