Genes affected
DYNC2I1 (HGNC:21862): (dynein 2 intermediate chain 1) This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD) and may facilitate the formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes including cell cycle progression, signal transduction, apoptosis, and gene regulation. The encoded protein contains four WD repeats and may play a role in the formation of cilia. Mutations in this gene have been associated with short-rib polydactyly and Jeune syndromes.

Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJul 16, 2024Variant summary: DYNC2I1 c.2284C>T (p.Arg762X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant was absent in 248022 control chromosomes. To our knowledge, no occurrence of c.2284C>T in individuals affected with Short-Rib Thoracic Dysplasia 8 With Or Without Polydactyly and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 446629). Based on the evidence outlined above, the variant was classified as pathogenic. -
