Genes affected

ECE1 (HGNC:3146): (endothelin converting enzyme 1) The protein encoded by this gene is involved in proteolytic processing of endothelin precursors to biologically active peptides. Mutations in this gene are associated with Hirschsprung disease, cardiac defects and autonomic dysfunction. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Sep 2009]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 1-21217735-G-A is Benign according to our data. Variant chr1-21217735-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2638445.Status of the report is criteria_provided_single_submitter, 1 stars.
