Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_001006657.2(WDR35):c.2162G>T(p.Arg721Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000867 in 1,614,016 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R721H) has been classified as Uncertain significance.

Cranioectodermal dysplasia 2;C3279792:Short-rib thoracic dysplasia 7 with or without polydactyly Uncertain:2
This sequence change replaces arginine with leucine at codon 721 of the WDR35 protein (p.Arg721Leu). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and leucine. This variant is present in population databases (rs370797645, ExAC 0.009%). This variant has not been reported in the literature in individuals affected with WDR35-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). 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. -

Inborn genetic diseases Uncertain:1
The c.2162G>T (p.R721L) alteration is located in exon 20 (coding exon 20) of the WDR35 gene. This alteration results from a G to T substitution at nucleotide position 2162, causing the arginine (R) at amino acid position 721 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
