Variant summary

Our verdict is Pathogenic. The variant received 4 ACMG points: 4P and 0B. PM3PP1PP4

This summary comes from the ClinGen Evidence Repository: The NM_213599.3: c.172C>T variant in ANO5 is a missense variant predicted to cause substitution of arginine by tryptophan at amino acid 58 (p.Arg58Trp). This variant has been detected in at least seven individuals with limb girdle muscular dystrophy or persistent hyperCKemia, including in unknown phase with a pathogenic variant (c.191dup x2, 1.0 pts, PMID:22499103, 30564623, LOVD Individual #00220701) and confirmed in trans with a pathogenic variant (c.2018A>G p.(Tyr673Cys), 1.0 pt, PMID:23055322; c.148C>T p.(Arg50Ter), 1.0 pt, PMID:30564623, LOVD Individual #00078872). Three individuals were homozygous for the variant, all of whom experienced progressive muscle weakness or showed myopathic or dystrophic signs on muscle biopsy (1.0 pt, PMID:31353849, 27854218) (PM3_Very Strong). At least one patient with this variant displayed progressive limb girdle muscle weakness (PP4). The variant has also been reported to segregate with autosomal recessive LGMD in one affected family member (PP1; PMID:23055322). The Grpmax filtering allele frequency for this variant is 0.002728 in gnomAD v4.1.0 exomes (the lower bound of the 95% confidence interval of 23/5762 Middle Eastern chromosomes), which is higher than the threshold of 0.001 for BS1. The Middle Eastern genetic ancestry group also includes three homozygous individuals. However, in light of the overall evidence for this variant and the potential for late onset and subclinical presentation, the LGMD VCEP considers this variant a BS1 exception. The computational predictor REVEL gives a score of 0.572 (PP3, BP4 not met). In summary, this variant meets the criteria to be classified as Pathogenic for autosomal recessive limb girdle muscular dystrophy based on the ACMG/AMP criteria applied, as specified by the ClinGen LGMD VCEP (LGMD VCEP specifications version 1.0.0; 06/24/2025): PM3_Very Strong, PP4, PP1.

Genes affected
ANO5 (HGNC:27337): (anoctamin 5) This gene encodes a member of the anoctamin family of transmembrane proteins. The encoded protein is likely a calcium activated chloride channel. Mutations in this gene have been associated with gnathodiaphyseal dysplasia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]
