Labcorp Genetics (formerly Invitae), Labcorp

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg547*) in the ANO5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ANO5 are known to be pathogenic (PMID: 21186264, 23606453, 25891276, 30919934). This variant is present in population databases (rs747719953, gnomAD 0.006%). This premature translational stop signal has been observed in individuals with autosomal recessive limb-girdle muscular dystrophy (PMID: 23606453, 25891276). ClinVar contains an entry for this variant (Variation ID: 288832). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

SIB Swiss Institute of Bioinformatics

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:curation

This variant is interpreted as a Likely Pathogenic, for Limb-girdle muscular dystrophy 2L, Autosomal Recessive inheritance. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PVS1-Strong => PVS1 downgraded in strength to Strong. -
