Genes affected

ELN (HGNC:3327): (elastin) This gene encodes a protein that is one of the two components of elastic fibers. Elastic fibers comprise part of the extracellular matrix and confer elasticity to organs and tissues including the heart, skin, lungs, ligaments, and blood vessels. The encoded protein is rich in hydrophobic amino acids such as glycine and proline, which form mobile hydrophobic regions bounded by crosslinks between lysine residues. Degradation products of the encoded protein, known as elastin-derived peptides or elastokines, bind the elastin receptor complex and other receptors and stimulate migration and proliferation of monocytes and skin fibroblasts. Elastokines can also contribute to cancer progression. Deletions and mutations in this gene are associated with supravalvular aortic stenosis (SVAS) and autosomal dominant cutis laxa.

ELN-AS1 (HGNC:40212): (ELN antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.58).
• BP6: Variant 7-74060425-C-T is Benign according to our data. Variant chr7-74060425-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 383752.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-4.3 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000342 (50/1461832) while in subpopulation AMR AF = 0.000626 (28/44722). AF 95% confidence interval is 0.000444. There are 0 homozygotes in GnomAdExome4. There are 18 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAd4 at 6 AD gene.
