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 made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.15813825).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000105 (16/152156) while in subpopulation AFR AF= 0.000386 (16/41436). AF 95% confidence interval is 0.000242. There are 0 homozygotes in gnomad4. There are 8 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 16 AD gene.

The c.164G>A (p.R55H) alteration is located in exon 1 (coding exon 1) of the EMILIN1 gene. This alteration results from a G to A substitution at nucleotide position 164, causing the arginine (R) at amino acid position 55 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
