which encodes a type I activin receptor serine/threonine kinase in 21% of DIPG samples. in this otherwise incurable disease. Recent high-throughput sequencing approaches have revealed a striking prevalence of K27M mutations in the genes encoding the histone variants H3.3 (and 8/26 (31%) (Determine 1a). These were not found in concert with mutations in the chaperones… Continue reading which encodes a type I activin receptor serine/threonine kinase in 21%
