Genes affected

WDR35 (HGNC:29250): (WD repeat domain 35) 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. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. Two patients with Sensenbrenner syndrome / cranioectodermal dysplasia (CED) were identified with mutations in this gene, consistent with a possible ciliary function.[provided by RefSeq, Sep 2010]

WDR35 participates in the retrograde IFT associated to cell cilium assembly and maintenance mainly through formation (along with IFT43) of the IFT-A complex. Although homozygous and compound heterozygous mutations in this gene usually lead to heterogenous clinical features, they have also been related to the distinct CED2 (OMIM 613610) and SRTD7 (OMIM 614091) syndromes. CED2 main features are craniosynostosis, dolichocephaly, narrow rib cage, short limbs, brachydactyly, and ectodermal defects (e.g., sparse hair, and nail and dental anomalies) whereas SRTD7 includes constricted thoracic cage, short ribs, and shortened tubular bones. Most patients with any of these syndromes appear to show normal intelligence and have no brain anomalies; however, two patients with developmental delay -- one featuring cortical atrophy, lobe defects, and ventriculomegaly and the other mega cisterna magna and slight cortical atrophy -- have been reported. Next generation sequencing: We focused on homozygous variants with a population frequency <0.01% and predicted to be pathogenic, likely pathogenic or variant of uncertain significance (VUS) by the SIFT, PANTHER, Mutation Taster 2, PhD-SNP, PROVEAN, and PolyPhen-2 platforms. Sequence conservation was evaluated by PhyloP, PhastCons and GERP scores; while MuPro and CFSSP from ExPASy were used to predict changes in the protein secondary structure. Results: The WDR35 mutation c.1415G>A also was a homozygous missense variant resulting in p.Arg472Gln. The total read depth for this variant was 62x (GQX= 99). This variant has not yet been reported in NHLBI Exome Sequencing Project (ESP) or ClinVar databases; but ExAC browser reported five alleles (5/121400, 0.00004119) with the same but heterozygous variant. This change is predicted to be likely pathogenic by Polyphen-2, PANTHER and Mutation tasting 2, whereas analysis by PROVEAN, SIFT and PhD-SNP considered this substitution to be neutral. Conservation scores (PhastCons = 1, PhyloP = 4.78, and GERP = 5.65) indicate that this position is evolutionary conserved. Accordingly, CFSSP tool denoted introduction of a new Î±-helix into the putative protein Î²-propeller domain 2 predicting stability decreasing from such missense variant. -
