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

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.94).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0273 (4154/152270) while in subpopulation NFE AF = 0.0342 (2326/68020). AF 95% confidence interval is 0.033. There are 86 homozygotes in GnomAd4. There are 2104 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 86 Unknown gene
