The c.214C>T (p.R72W) alteration is located in exon 3 (coding exon 3) of the CEP97 gene. This alteration results from a C to T substitution at nucleotide position 214, causing the arginine (R) at amino acid position 72 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with CEP97-related conditions. This variant is present in population databases (rs547567941, gnomAD 0.06%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 72 of the CEP97 protein (p.Arg72Trp). -
