Genes affected
EMILIN1 (HGNC:19880): (elastin microfibril interfacer 1) This gene encodes an extracellular matrix glycoprotein that is characterized by an N-terminal microfibril interface domain, a coiled-coiled alpha-helical domain, a collagenous domain and a C-terminal globular C1q domain. The encoded protein associates with elastic fibers at the interface between elastin and microfibrils and may play a role in the development of elastic tissues including large blood vessels, dermis, heart and lung.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.22286615).
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00000958 (14/1461470) while in subpopulation MID AF = 0.000347 (2/5768). AF 95% confidence interval is 0.0000729. There are 0 homozygotes in GnomAdExome4. There are 6 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 5 AD gene.

The c.343G>A (p.D115N) alteration is located in exon 3 (coding exon 3) of the EMILIN1 gene. This alteration results from a G to A substitution at nucleotide position 343, causing the aspartic acid (D) at amino acid position 115 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
