Genes affected

DYNC1I2 (HGNC:2964): (dynein cytoplasmic 1 intermediate chain 2) This gene encodes a member of the dynein intermediate chain family. The encoded protein is a non-catalytic component of the cytoplasmic dynein 1 complex, which acts as a retrograde microtubule motor to transport organelles and vesicles. A pseudogene of this gene is located on chromosome 10. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

Collection Method:clinical testing

The c.266C>G (p.S89C) alteration is located in exon 5 (coding exon 4) of the DYNC1I2 gene. This alteration results from a C to G substitution at nucleotide position 266, causing the serine (S) at amino acid position 89 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
