Lumbar and cervical spinal fusions are more commonly performed than thoracic fusions. Uncapped telomeres also result in chromosomal fusions. This database is called Mitelman Database of Chromosome Aberrations and Gene Fusions in Cancer. SYNS1 is different from SYM1 by causing hip and vertebral fusions. ALK inhibitors such as crizotinib showed to be effective against tumors harboring ALK fusions. The variability occurs as a result of chromosome fusions or disassociations. Clinical data supports the use of crizotinib in lung cancer patients with "ROS1" gene fusions. It engendered subgenres and fusions, including synth-pop. All of the kinase fusions retain the tyrosine kinase domain of "ROS1" . Jazz saw a resurgence as black British musicians created new fusions such as Acid Jazz. Potentially unstable spines will need "spine fusions". Alsina's music generally falls into the Alternative R&B category that predominantly involves fusions with Hip-hop. Fusions of individual bones into strong, rigid structures are characteristic. The average length of hospital stay for spinal fusions is 3.7 days. The periodic fusions permit mutual reactivation of otherwise lethally damaged protocells.
