Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1917C>A (p.S639R) alteration is located in exon 14 (coding exon 13) of the CCDC114 gene. This alteration results from a C to A substitution at nucleotide position 1917, causing the serine (S) at amino acid position 639 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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: "Probably Damaging"; Align-GVGD: "Class C0"). 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. ClinVar contains an entry for this variant (Variation ID: 582012). This variant has not been reported in the literature in individuals affected with CCDC114-related conditions. This variant is present in population databases (rs146521880, gnomAD 0.02%). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 639 of the CCDC114 protein (p.Ser639Arg).
