Genes affected

ERMARD (HGNC:21056): (ER membrane associated RNA degradation) The protein encoded by this gene contains 2 transmembrane domains near the C-terminus and is localized in the endoplasmic reticulum. Knockout of this gene in developing rat brain showed that it may be involved in neuronal migration. Mutations in this gene are associated with periventricular nodular heterotopia-6 (PVNH6). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2013]

DYNLT2 (HGNC:11695): (dynein light chain Tctex-type 2) Predicted to enable dynein intermediate chain binding activity. Predicted to be involved in microtubule-based movement. Predicted to be located in cytosol and sperm flagellum. Predicted to be extrinsic component of membrane. Predicted to be part of cytoplasmic dynein complex. Predicted to be active in cytoplasm.
