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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00000616 (9/1461506) while in subpopulation EAS AF = 0.000202 (8/39700). AF 95% confidence interval is 0.0000993. There are 0 homozygotes in GnomAdExome4. There are 5 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
