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]

The c.338C>T (p.T113M) alteration is located in exon 6 (coding exon 5) of the DYNC1I2 gene. This alteration results from a C to T substitution at nucleotide position 338, causing the threonine (T) at amino acid position 113 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
