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]

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with KIAA1549-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with cysteine at codon 1932 of the KIAA1549 protein (p.Arg1932Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. -
