Genes affected
DYNC2H1 (HGNC:2962): (dynein cytoplasmic 2 heavy chain 1) This gene encodes a large cytoplasmic dynein protein that is involved in retrograde transport in the cilium and has a role in intraflagellar transport, a process required for ciliary/flagellar assembly. Mutations in this gene cause a heterogeneous spectrum of conditions related to altered primary cilium function and often involve polydactyly, abnormal skeletogenesis, and polycystic kidneys. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jan 2010]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2021The c.12664A>C (p.I4222L) alteration is located in exon 88 (coding exon 88) of the DYNC2H1 gene. This alteration results from a A to C substitution at nucleotide position 12664, causing the isoleucine (I) at amino acid position 4222 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
