DiseaseAssertion: Distal myopathy

FamilyInfo: Figure 1, similar distal muscle weakness in four relatives. Patients I.2 and II.2 experienced foot drop while walking. Patient III.2 muscle biopsy findings suggestive of core myopathy suggested a disorder similar to his youngest sister. Patient IV.1 displayed a less progressive muscular phenotype than her older relatives and tested negative for the mutation in RYR1

CasePresentingHPOs: HP:0001761, HP:0008994, HP:0002650

"Pes cavus, Proximal muscle weakness in lower limbs, Scoliosis"

CaseHPOFreeText: stepping gait

CasePreviousTesting: muscle biopsy showed fiber size variability, increased internal nuclei and histochemical evidence of eccentric core-like lesions, Analysis of RYR1 revealed a heterozygous c.880G > A:p.(Glu294Lys) mutation

GenotypingMethod: Amplicon-based Sanger sequencing, MotorPlex used to analyze a large set of genes that cause known forms of non-syndromic muscle disorders
