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 Likely_benign. Variant got -1 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.99

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000759 (111/1461738) while in subpopulation NFE AF= 0.0000944 (105/1111912). AF 95% confidence interval is 0.0000795. There are 0 homozygotes in gnomad4_exome. There are 52 alleles in male gnomad4_exome subpopulation. Median coverage is 31. 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 5 AD gene.

The c.275G>A (p.C92Y) alteration is located in exon 2 (coding exon 2) of the EMILIN1 gene. This alteration results from a G to A substitution at nucleotide position 275, causing the cysteine (C) at amino acid position 92 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
