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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.2297T>C (p.M766T) alteration is located in exon 18 (coding exon 17) of the ECEL1 gene. This alteration results from a T to C substitution at nucleotide position 2297, causing the methionine (M) at amino acid position 766 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
