The best available variant frequency is uninformative because it is below the disease allele frequency. Found in at least one symptomatic patient. Predicted to have a damaging effect on the protein. Statistically enriched in patients compared to ethnically matched controls. Occurs in three or more cases with a recessive pathogenic variant in the same gene. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The missense variant c.1733T>C (p.Phe578Ser) in the ANO5 gene has been reported previously in heterozygous and compound heterozygous states in many individuals affected with limb-girdle muscular dystrophy (Hicks et al., 2011; Savarese et al., 2015). This variant is reported with the allele frequency (0.01%) in the gnomAD Exomes. It is submitted to ClinVar as Pathogenic/ Likely pathogenic/ Uncertain significance. However, functional evidence on its pathogenicity is not available. The amino acid Phe at position 578 is changed to a Ser changing protein sequence and it might alter its composition and physico-chemical properties. Multiple lines of computational evidence (Polyphen - Damaging, SIFT - Damaging and MutationTaster - Disease causing) predict a damaging effect on protein structure and function for this variant. The amino acid change p.Phe578Ser in ANO5 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Likely Pathogenic. In the absence of another reportable variant, the molecular diagnosis is not confirmed. -

Collection Method:clinical testing

This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 578 of the ANO5 protein (p.Phe578Ser). This variant is present in population databases (rs137854526, gnomAD 0.1%). This missense change has been observed in individual(s) with autosomal recessive ANO5-related conditions (PMID: 21186264, 23041008, 23663589, 23670307, 25891276). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 140553). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ANO5 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
