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]

The CFAP410 c.269G>A variant is predicted to result in the amino acid substitution p.Arg90Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.023% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 90 of the CFAP410 protein (p.Arg90Gln). 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1002243). This variant has not been reported in the literature in individuals affected with CFAP410-related conditions. This variant is present in population databases (rs567435284, gnomAD 0.02%). -
