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), LabcorpDec 11, 2023This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 17 of the WDR60 protein (p.Asp17Asn). This variant is present in population databases (rs374477653, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with WDR60-related conditions. ClinVar contains an entry for this variant (Variation ID: 1680637). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
