    1. affected boy (IV-1; 11 years)

      Case#: IV-1, male, 11 y.o, Pakistani

      DiseaseAssertion: Limb-girdle muscular dystrophy (LGMD2F), sarcoglycanopathy

      FamilyInfo: Consanguineous parents, both described as healthy and showing no abnormality. Three unaffected siblings were also reported: IV-2 (male, 10 y.o), IV-4 (male, 7 y.o), and IV-5 (female, 1.5 y.o). A deceased sister is included on the pedigree, but no details about this individual were reported. See Figure 1.

      CasePresentingHPOs: HP:0001288, HP:0002650, HP:0003547, HP:0003749, HP:0001655

      CaseHPOFreeText: Reduced weight gain noted at 3-4 y.o. Mild cardiac hypertrophy observed on cardiac review (additional echocardiography results reported in "Echocardiography" section). Additional phenotypic information reported in Supplementary Table 1.

      CaseNotHPOs: HP:0009077, HP:0000703, HP:0001382, HP:0000365, HP:0001510, HP:0001249, HP:0000478, HP:0030148, HP:0011675

      CaseNotHPOFreeText: Extensor muscles of the wrist, toes flexors, and hip abductors noted to be relatively normal. Additional phenotypic information reported in Supplementary Table 1.

      MotorAchievement: Sat without assistance at 8 months of age, walked at 15 months of age, ran at 1.5 months of age. Never jumped or hopped. Frequent falls noted, as well as difficulty in walking and climbing stairs since 3 y.o.

      CreatineKinase: 18SU (normal: 20SU for children, 10SU for adults) (see Supplementary Table 1). No assertion was made by the authors regarding whether this represents a normal or decreased CK level.

      PreviousTesting: Thyroid stimulating hormone: 2.3mU/L (normal: <0.6mU/L); Serum VZV IgG: 286mlU/ml (normal: >150mlU/ml); IGF-1:186 ng/μl (normal: 102-520 ng/μl for males, 14 y.o); PRL: 202 ng/dl (normal: 42.5-414 ng/dl for males); Vitamin D: 47nmol/L (normal: 25-50 nmol/L); Free T4: 17.0 pmol/L (normal:10.8-19.0 pmol/L) (see Supplementary Table 1)

      GenotypingMethod: (1) Targeted next generation sequencing of 31 genes associated with LGMD from proband genomic DNA extracted from peripheral blood sample; (2) Sanger sequencing of genomic DNA extracted from peripheral blood samples to confirm SGCD variant of interest in proband and three family members (III-3, III-4, IV-4). Variant was identified in homozygosity in the proband, in heterozygosity in each of the parents, and was not present in the unaffected sibling (IV-4).
