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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -20 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.82).

BP6

Variant 2-232484900-G-C is Benign according to our data. Variant chr2-232484900-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 128956.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr2-232484900-G-C is described in Lovd as [Likely_benign].

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0088 (1341/152318) while in subpopulation NFE AF= 0.0142 (964/68016). AF 95% confidence interval is 0.0134. There are 12 homozygotes in gnomad4. There are 643 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.

BS2

High Homozygotes in GnomAd4 at 12 AR gene
