Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_144573.4(NEXN):ā€‹c.2015A>Gā€‹(p.Glu672Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000206 in 1,456,370 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E672K) has been classified as Uncertain significance.

Genes affected
NEXN (HGNC:29557): (nexilin F-actin binding protein) This gene encodes a filamentous actin-binding protein that may function in cell adhesion and migration. Mutations in this gene have been associated with dilated cardiomyopathy, also known as CMD1CC. Alternatively spliced transcript variants have been described.[provided by RefSeq, Feb 2010]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineAug 17, 2015The p.Glu672Gly variant in NEXN has not been previously reported in individuals with cardiomyopathy or in large population studies. Computational prediction too ls and conservation analysis suggest that this variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In s ummary, the clinical significance of the p.Glu672Gly variant is uncertain. -
