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]

The c.5771C>T (p.S1924L) alteration is located in exon 20 (coding exon 20) of the KIAA1549 gene. This alteration results from a C to T substitution at nucleotide position 5771, causing the serine (S) at amino acid position 1924 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
