Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 438 of the CCDC114 protein (p.Asp438Asn). This variant is present in population databases (rs199600077, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with CCDC114-related conditions. ClinVar contains an entry for this variant (Variation ID: 454964). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The asparagine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The ODAD1 c.1312G>A; p.Asp438Asn variant (rs199600077), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 454964). This variant is found in the general population with an overall allele frequency of 0.014% (38/281214 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is neutral (REVEL: 0.004). Due to limited information, the clinical significance of this variant is uncertain at this time. -
