    1. 74-year-old male was admitted to the Department of Cardiology, Daejeon St. Mary’s Hospital (Daejeon, Korea), for the evaluation of exertional dyspnea (New York Heart Association (NYHA) functional class III), palpitations, and bilateral leg pitting edema for several months.

      Case#: Pedigree I-1; 74-year-old Korean male; admitted for dyspnea (NYHA III), palpitations, and bilateral pitting leg edema over several months

      DiseaseAssertion: Idiopathic restrictive cardiomyopathy (RCM) with biatrial enlargement, in a family with MYBPC3-related cardiomyopathy

      FamilyInfo: Family history of heart disease with two affected daughters (II-2 and II-4), both heterozygous for the same variant and both diagnosed with HCM. Unaffected granddaughter (III-3) tested negative. Both daughters showed asymmetric septal hypertrophy on TTE (18 mm and 17 mm) with mildly dilated LA; daughter II-2 had grade I diastolic dysfunction and mild exertional chest discomfort. CMR confirmed reverse septal curvature hypertrophy consistent with HCM in both daughters, with no LGE in either.⁠

      ParentalTesting: Not performed; the proband is the index case in generation I; his parents were not evaluated. Phase established only through the daughters and granddaughter.

      CaseHPOFreeText: Exertional dyspnea NYHA class III, palpitations, and bilateral leg pitting edema for several months; dyspnea refractory to heart failure medication, with pulmonary venous congestion. ECG and Holter: atrial fibrillation with rare premature ventricular complexes. TTE: RCM with biatrial enlargement and small pericardial effusion. CMR: normal LV chamber size, borderline diffuse LV hypertrophy, very large atria, extensive transmural LGE in the apical wall and mid-myocardial patchy LGE in the ventricular septum. Coronary angiogram normal; no secondary cause of RCM found.⁠

      CaseNotHPOs: HP:0000822; HP:0000819; HP:0001658; HP:0001678

      CaseNotHPOFreeText: Coronary angiogram normal, so no obstructive coronary disease. No secondary cause of RCM identified; no inflammatory, infiltrative, or systemic disease found. No AV block; the rhythm disturbance was atrial fibrillation.

      CasePreviousTesting: Whole exome sequencing (Agilent SureSelect XT Human All Exon v5, Illumina HiSeq2500, GATK. Sanger sequencing of family members showed only the MYBPC3 variant tracked with disease; the other four (KALRN c.1702C>T, KCNH2 c.442C>T, SKI c.30T>G, TTN c.54293T>C) did not correlate with phenotype.⁠

      Genotyping Method: WES in the proband, with annotation via dbNSFP and Ensembl VEP; Sanger sequencing confirmed the MYBPC3 frameshift in the proband (I-1), daughters II-2 and II-4, and its absence in granddaughter III-3 (Fig. 3B).⁠

      FunctionalAnalysis: None performed. CMR showed extensive LGE in the apical LV, and the authors propose that advanced myocardial fibrosis in end-stage HCM can provoke myocardial atrophy, explaining the relatively normal LV chamber size with a predominantly restrictive phenotype hypothesis.⁠

      Variant: MYBPC3 NM_000256.3:c.3313_3314insGG (p.Ala1105Glyfs*85); heterozygous frameshift insertion; absent from gnomAD and the Korean Reference Genome Database.

      gnomAD: Absent per the authors' check of gnomAD as of 8 November 2020, and absent from KRGDB.

      AdditionalInfo: Authors conclude the MYBPC3 frameshift is the pathogenic variant, with the same allele producing RCM in the proband and HCM in both daughters; an example of pleiotropy and variable expressivity within one family. The frameshift has previously been reported in Korean HCM. Poor-prognosis features in RCM cited by the authors: male sex, age over 70, high NYHA class, and LA dimension >60 mm.

      DiseaseAssertion: Noonan syndrome (PTPN11) with sarcomeric hypertrophic cardiomyopathy (MYBPC3); non-obstructive HCM, mild phenotype

      FamilyInfo: Father carries the MYBPC3 c.1790G>A variant and has HCM; the PTPN11 variant was absent in both parents, consistent with de novo. Both parents and the proband's brothers underwent full cardiologic evaluation, no cardiovascular disease in the other family members. Parents declined genetic testing of the underage siblings. Grandparents (I-1, I-2) and II-2, II-3 have unknown phenotypes (pedigree Fig. 2).

      ParentalTesting: Both parents genotyped for the two proband variants (Table 1). Father heterozygous for MYBPC3 c.1790G>A; neither parent carries PTPN11 c.1510A>G, supporting de novo status. Phase between the two variants therefore established as in trans (different genes).

      Gene: MYBPC3

      AdditionalInfo: Authors describe this as the first reported young adult with HCM and mild NS carrying variants in both PTPN11 and MYBPC3. Note the terminology problem: the abstract calls them "compound heterozygous," but the variants are in different genes on different chromosomes, so this is digenic (double heterozygosity), not compound heterozygosity. The authors argue the mild phenotype contrasts with the usual expectation that multiple sarcomeric hits worsen the disease, and that red flags justified the broad panel.

Phenotypic cumulative lifetime risk was 71% for Pheo/PGL, 15% for hemangioblastoma, 33% for retinal angioma, 3% for renal cell carcinoma, and 3% for pancreatic cysts. 6 members of the family (all deceased; 4 males, 2 females) had suspected VHL and 2 (males) of these were suspected to have had Pheo/PGL.

    1. Thirty-five unrelated patients suspected of having von Hippel-Lindau disease were analyzed and 32 VHL gene variants were found in 35 patients using PCR and SSCP by peripheral blood leukocytes. An association of clear cell renal carcinoma development with a relatively high loss of structural stability in VHL protein missense mutations was discovered. A mutation, F76del(c.227_229del) (noted as g.941_943delTCT in the paper originally) was found in a patient with cerebellar hemangioblastomas, renal cyst, and pancreatic cyst, the pateints age on onset was 31 years old. No family history was mentioned, other than a note of no familial antecedents with the disease.
