Comment when marking as ready: On Manchester diagnostic panel and DDG2PCreated: 11 Feb 2016, 11:22 a.m.
Small number of variants reported to be pathogenic on ClinVar detected in an array of different patient cohorts including AF BS epilepsy cardiomyopathy conduction defects and epileptic encephalopathy. PMID 29758173 reports lack of genotype or phenotype correlations in families with BS or SADS with previously thought to be pathogenic variants in SCN1B.Created: 25 Jan 2019, 1:15 p.m.
