Genes affected

LDB3 (HGNC:15710): (LIM domain binding 3) This gene encodes a PDZ domain-containing protein. PDZ motifs are modular protein-protein interaction domains consisting of 80-120 amino acid residues. PDZ domain-containing proteins interact with each other in cytoskeletal assembly or with other proteins involved in targeting and clustering of membrane proteins. The protein encoded by this gene interacts with alpha-actinin-2 through its N-terminal PDZ domain and with protein kinase C via its C-terminal LIM domains. The LIM domain is a cysteine-rich motif defined by 50-60 amino acids containing two zinc-binding modules. This protein also interacts with all three members of the myozenin family. Mutations in this gene have been associated with myofibrillar myopathy and dilated cardiomyopathy. Alternatively spliced transcript variants encoding different isoforms have been identified; all isoforms have N-terminal PDZ domains while only longer isoforms (1, 2 and 5) have C-terminal LIM domains.

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The c.576G>A variant affects a non-conserved nucleotide, resulting in synonymous amino acid change. 5/5 in silico programs via Alamut predict that this variant does not affect normal splicing. This variant is found in 87/119636 control chromosomes from the large and broad populations of ExAC at a frequency of 0.0007272, which is about 29 times greater than the maximal expected frequency of a pathogenic allele (0.000025), suggesting this variant is benign. In addition, multiple clinical laboratories have classified this variant as benign. One internal sample carrying this variant was also found to carry a pathogenic variant in TTR gene (p.V142I) further supporting benign outcome. Taken together, this variant has been classified as Benign. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
