Genes affected

DYNLT2B (HGNC:28482): (dynein light chain Tctex-type 2B) Dyneins are a group of microtubule-activated ATPases that function as molecular motors. They are divided into two subgroups of axonemal and cytoplasmic dyneins. The cytoplasmic dyneins function in intracellular motility, including retrograde axonal transport, protein sorting, organelle movement, and spindle dynamics. Molecules of conventional cytoplasmic dynein are comprised of 2 heavy chain polypeptides and a number of intermediate and light chains. This gene encodes a subunit of the human cytoplasmic dynein-2 complex. Mutations in this gene are associated with short-rib thoracic dysplasia 17 with or without polydactyly. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2017]

TM4SF19-DYNLT2B (HGNC:49190): (TM4SF19-DYNLT2B readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring transmembrane 4 L six family member 19 (TM4SF19) and Tctex1 domain containing 2 (TCTEX1D2) genes on chromosome 3. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus not expected to produce a protein product. [provided by RefSeq, Mar 2011]
