Invitae RCV001865564 SCV002133410 uncertain significance Developmental and epileptic encephalopathy, 1; Autosomal recessive spinocerebellar ataxia 12 2021-08-05 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with asparagine at codon 108 of the WWOX protein (p.Asp108Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs747575799, ExAC 0.04%). This variant has not been reported in the literature in individuals affected with WWOX-related conditions. ClinVar contains an entry for this variant (Variation ID: 432407). 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: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). 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.
Ambry Genetics RCV002527142 SCV003747870 uncertain significance Inborn genetic diseases 2021-06-22 criteria provided, single submitter clinical testing The c.322G>A (p.D108N) alteration is located in exon 4 (coding exon 4) of the WWOX gene. This alteration results from a G to A substitution at nucleotide position 322, causing the aspartic acid (D) at amino acid position 108 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
