Development of a Comprehensive Sequencing Assay for Inherited Cardiac Condition Genes, Pua et al, Journal of Cardiovascular Translational Research, online Feb 2016 (doi:10._1007/_s12265-016-9673-5). The panel contains disease-causing, putatively pathogenic, research and phenocopy genes, and it is unclear from the publication whether this gene falls into the disease-causing category. No. of mutations indicated in supplemental table = 3. HGMD: 24 DM variants associated mainly with paeditaric cataracts though some patients can have cardiomyopathy and myopathy. Some truncating variants associated with cardiomyopathy. A number of variants have functional studies eg: Raju (2013) Biochem Biophys Res Commun 430: 107 PubMed: 23194663 of a variant assoc with cataracts, cardiomyopathy and myopathy. van der Smagt Clin Genet. 2014 Apr;85(4):381-5. doi: 10.1111/cge.12169: present a case of adult onset DCM.Created: 25 Mar 2019, 4:27 p.m.
Mode of inheritance
BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Variants in this GENE are reported as part of current diagnostic practice
Mode of inheritance for gene: CRYAB was changed from BOTH monoallelic and biallelic, autosomal or pseudoautosomal to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Phenotypes for gene: CRYAB were changed from Myopathy, myofibrillar, fatal infantile hypertrophy, alpha B crystallin related, 613869; Cardiomyopathy, dilated, 1II, to Cardiomyopathy, dilated, 1II, OMIM:615184; Myopathy, myofibrillar, 2, OMIM:608810
