Our verdict is Benign. Variant got -14 ACMG points: 0P and 14B. BP4_StrongBP6BP7BS1BS2
The NM_000501.4(ELN):c.159A>T(p.Gly53Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000039 in 1,613,970 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).
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.

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.
