For a general phenotypic description and a discussion of genetic heterogeneity of dilated cardiomyopathy, see CMD1A (115200).
Schonberger et al. (2005) reported a 3-generation Portuguese family in which 16 individuals had dilated cardiomyopathy (CMD). The pedigree was consistent with autosomal dominant inheritance and age-related penetrance, with age of onset between 25 and 47 years of age.
In a 3-generation Portuguese family segregating autosomal dominant dilated cardiomyopathy, Schonberger et al. (2005) performed genomewide linkage analysis and excluded linkage to all known CMD genes and loci, whereas several close markers on chromosome 7q22.3-q31.1 segregated with the disease (maximum lod score, 4.20 at D7S471 and D7S501). Recombination events defined a 9.73-Mb disease interval between D7S2545 and D7S2554. No mutations were identified in the coding exons of 3 candidate genes, LAMB1 (150240), LAMB4 (616380), and PIK3CG (601232).

Dear OMIM User,
To ensure long-term funding for the OMIM project, we have diversified our revenue stream. We are determined to keep this website freely accessible. Unfortunately, it is not free to produce. Expert curators review the literature and organize it to facilitate your work. Over 90% of the OMIM's operating expenses go to salary support for MD and PhD science writers and biocurators. Please join your colleagues by making a donation now and again in the future. Donations are an important component of our efforts to ensure long-term funding to provide you the information that you need at your fingertips.
Thank you in advance for your generous support,
Ada Hamosh, MD, MPH
