Case1049: 5 yrs onset, United States, Black
CasePresentingHPOs: HP:0006785, HP:0003236 (Limb-girdle muscular dystrophy, Elevated serum creatine kinase)
HPOsFreeText: N/A
CaseNotHPOs: N/A
NotHPOsFreeText: N/A
CaseAddInfo: Affected brother, sister, and half-brother, Genotype confirmed in proband and affected brother only
CasePreviousTesting: Serum CK levels 8,000 - 18,000 UI/l; Genetic testing also included DMD, FKRP, DM1, DM2;
CaseGenotypingMethod: DNA was collected from peripheral blood or saliva samples. WES was performed and processed though a pipeline before aligning the reads and analyzing the candidate gene list for any variants using the various inheritance patterns. Screening was performed based on in silico predictors with a liberal threshold to filter variants before PCR amplification and Sanger sequencing confirmed the pathogenic mutations.
