Genes affected

CFAP410 (HGNC:1260): (cilia and flagella associated protein 410) Four alternatively spliced transcript variants encoding four different isoforms have been found for this nuclear gene. All isoforms contain leucine-rich repeats. Three of these isoforms are mitochondrial proteins and one of them lacks the target peptide, so is not located in mitochondrion. This gene is down-regulated in Down syndrome (DS) brain, which may represent mitochondrial dysfunction in DS patients. [provided by RefSeq, Sep 2012]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 73 of the CFAP410 protein (p.Arg73His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with CFAP410-related conditions. ClinVar contains an entry for this variant (Variation ID: 1053006). 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 histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant disrupts the p.Arg73 amino acid residue in CFAP410. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 26167768, 26974433, 27596865, 28041643). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. -
