Genes affected

DYNC2I2 (HGNC:28296): (dynein 2 intermediate chain 2) 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), which may facilitate 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. Defects in this gene are a cause of short-rib thoracic dysplasia 11 with or without polydactyly. [provided by RefSeq, Mar 2014]

This variant has not been reported in the literature in individuals affected with WDR34-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant is present in population databases (rs760310956, gnomAD 0.003%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 507 of the WDR34 protein (p.Val507Ala). -
