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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PP5: Variant 2-232485253-CCCAT-AGC is Pathogenic according to our data. Variant chr2-232485253-CCCAT-AGC is described in ClinVar as [Pathogenic]. Clinvar id is 242402.Status of the report is no_assertion_criteria_provided, 0 stars.
