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]

The c.1771T>C (p.S591P) alteration is located in exon 15 (coding exon 15) of the ECE1 gene. This alteration results from a T to C substitution at nucleotide position 1771, causing the serine (S) at amino acid position 591 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
