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.286C>G (p.P96A) 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 286, causing the proline (P) at amino acid position 96 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
