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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.79).
BP6
Variant 2-232481151-G-A is Benign according to our data. Variant chr2-232481151-G-A is described in ClinVar as Benign. ClinVar VariationId is 128953.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-1.65 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0157 (2385/152346) while in subpopulation NFE AF = 0.0238 (1617/68026). AF 95% confidence interval is 0.0228. There are 39 homozygotes in GnomAd4. There are 1115 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 39 AR gene
