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.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.53).
BP6
Variant 7-74036580-A-T is Benign according to our data. Variant chr7-74036580-A-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 453323.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=1}.
BP7
Synonymous conserved (PhyloP=3.25 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000397 (58/1461852) while in subpopulation MID AF= 0.00104 (6/5768). AF 95% confidence interval is 0.000453. There are 1 homozygotes in gnomad4_exome. There are 27 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High AC in GnomAd4 at 5 AD gene.
