Genes affected

NEBL (HGNC:16932): (nebulette) This gene encodes a nebulin like protein that is abundantly expressed in cardiac muscle. The encoded protein binds actin and interacts with thin filaments and Z-line associated proteins in striated muscle. This protein may be involved in cardiac myofibril assembly. A shorter isoform of this protein termed LIM nebulette is expressed in non-muscle cells and may function as a component of focal adhesion complexes. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010]

The p.K60N variant (also known as c.180G>C) is located in coding exon 3 of theNEBLgene. This alteration results from a G to C substitution at nucleotide position 180. The lysine at codon 60 is replaced by asparagine, an amino acid with some similar properties. Ã¢â‚¬â€¹Ã¢â‚¬â€¹In an initial publication associating NEBLwith dilated cardiomyopathy (DCM), this alteration was identified in a cohort of 260 individuals with DCM and absent in 600 control alleles. This alteration was found to be de novoin a proband with adult onset DCM. Authors subsequently developed a transgenic mouse model, and founder mice with this alteration developed severe heart failure at one year old. Embryos with this alteration did not survive, presenting the possibility of embryonic lethality with the p.K60N alteration(Purevjav E etal. J Am Coll Cardiol. 2010;56(18):1493-1502).However, a later publication denotes that the presence and frequency of this alteration in a large population based database from the Exome Sequencing Project (ESP) creates uncertainty regarding its pathogenicity (Andreasen C etal. Eur J Hum Genet. 2013;21(9):918-928). This variant was previously reported in dbSNP asrs41277374. Based on data from the NHLBI Exome Sequencing Project (ESP), the C-allele has an overall frequency of approximately0.52% (67/12998), having been observed in 0.71% (61/8594) of European American alleles, and in 0.14% (6/4404)of African American alleles studied. Based on data from the 1000 Genomes Project, the C-allele has an overall frequency of approximately0.18% (4/2184). The highest observed frequency was 1.12% (2/178) of Britishchromosomes studied. Based on protein sequence alignment, this amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be probably damaging and deleterious by PolyPhen and SIFT in silico analyses, respectively.Since supporting evidence for this variant is conflicting and limited at this time, its clinical significance remains unclear. -
