Genes affected

ECEL1 (HGNC:3147): (endothelin converting enzyme like 1) This gene encodes a member of the M13 family of endopeptidases. Members of this family are zinc-containing type II integral-membrane proteins that are important regulators of neuropeptide and peptide hormone activity. Mutations in this gene are associated with autosomal recessive distal arthrogryposis, type 5D. This gene has multiple pseudogenes on chromosome 2. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2014]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The ECEL1 c.997C>T (p.Arg333Ter) nonsense variant is predicted to result in the loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been identified in trans with a likely pathogenic variant in at least two unrelated individuals with a phenotype consistent with distal arthrogryposis type 5 (PMID: 23236030; 25173900; 33820833; 33672664). The highest frequency of this allele in the Genome Aggregation Database is 0.000459 in the African/African American population (version 3.1.2). This variant has been classified as pathogenic by at least three submitters in ClinVar and is observed in a homozygous state. Based on the available evidence, the c.997C>T (p.Arg333Ter) variant is classified as pathogenic for distal arthrogryposis type 5. -
