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.

Short-rib thoracic dysplasia 8 with or without polydactyly Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 13, 2022This sequence change creates a premature translational stop signal (p.Gln947Hisfs*89) in the WDR60 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 120 amino acid(s) of the WDR60 protein. This variant is present in population databases (rs748645101, gnomAD 0.03%). This premature translational stop signal has been observed in individual(s) with short-rib polydactyly syndrome (PMID: 29068549). ClinVar contains an entry for this variant (Variation ID: 446628). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
