The p.Ser555Ile variant in ANO5 has been reported in the compound heterozygous state in 6 individuals with limb-girdle muscular dystrophy and other myopathy phenotypes (Kuhn 2016 PMID: 26886200, Ylikallio 2016 PMID: 27911336, Nallamilli 2018 PMID: 30564623, Wu 2018 PMID: 29382405, Jarmula 2019 PMID: 31395899, Božović 2021 PMID: 34106991). It has also been identified in 0.02% (22/129024) of European non-Finnish chromosomes by gnomAD (http://gnomad.broadinstitute.org). However, this frequency is low enough to be consistent with a recessive allele frequency. This variant was identified through WGS in compound heterozygosity with a likely pathogenic variant in an adult male with adult-onset muscular dystrophy with mild distal weakness and hyperCKemia by the Broad Institute Rare Genomes Project. This variant has also been reported in ClinVar (Variation ID 286450). Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In vitro functional studies provide some evidence that this variant impacts protein function (Di Zanni 2020 PMID: 32112655); however, these types of assays may not accurately represent biological function. In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive ANO5-related muscle disease. ACMG/AMP Criteria applied: PM3_strong, PM2_supporting, PS3_supporting. -

This sequence change replaces serine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 555 of the ANO5 protein (p.Ser555Ile). This variant is present in population databases (rs375014127, gnomAD 0.02%). This missense change has been observed in individual(s) with autosomal recessive ANO5-related conditions (PMID: 26886200, 27911336, 30564623, 31395899). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 286450). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ANO5 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects ANO5 function (PMID: 32112655). For these reasons, this variant has been classified as Pathogenic. -

Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000286450, PS1_S). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000092, PM2_M). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 26886200, 27911336, PM3_M). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
