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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.006800264).

BP6

Variant 1-77926436-T-C is Benign according to our data. Variant chr1-77926436-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 201917.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000394 (60/152272) while in subpopulation EAS AF = 0.00926 (48/5184). AF 95% confidence interval is 0.00718. There are 0 homozygotes in GnomAd4. There are 37 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 60 AD gene.
