Myozenin 2 Is a Novel Gene for Human Hypertrophic Cardiomyopathy
PMID:17347475
Gene:MYOZ2
HGNC ID:1330
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.
CasePresentingHPOs:HP:0002094; HP:0001962; HP:0001677; HP:0001635; HP:0001639; HP:0001698
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.
ClinVar: 1473634
CAID: Not reported.
Gene:MYBPC3
HGNC: HGNC: 7551
PMID: 33803538
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.

CAID: CA391631478
gnomAD: Exact frequency not provided
AdditionalInfo: The patient's heart pumping ability was 70 %on ultrasound. Researchers classified his ACTC1 variant as a variant of uncertain significance meaning they were not sure whether it causes diseases.
subject (33-year-old female) showed regular psychophysical development
Case#: 33 year-old female; first cardiologic evaluation at age 24 (LV wall thickness 13 mm); re-evaluated at 33 after recurrent palpitations
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).
CasePresentingHPOs: HP:0001639; HP:0001962; HP:0004322; HP:0000271; HP:0001647; HP:0000508
CaseHPOFreeText: Regular psychophysical development. First echo at 24 showed mild increase in LV wall thickness (13 mm). At 33, presented with several episodes of palpitations; exam showed mild facial dysmorphisms (wide mouth, sloping forehead, prominent nasal bridge, prominent nose, low-set ears), short stature, and a systolic heart murmur. Echo: asymmetric LV hypertrophy, maximum wall thickness 16 mm at the anterior interventricular septum, mild mitral regurgitation, non-obstructive. No other cardiovascular signs.
CaseNotHPOs: HP:0001635; HP:0001650; HP:0001642; HP:0001250
CaseNotHPOFreeText: No heart failure, no LV outflow obstruction, no pulmonary stenosis, no other congenital heart defect. No intellectual disability; psychophysical development was regular. No other signs of cardiovascular disease on examination.
CasePreviousTesting: NGS panel of 325 cardiomyopathy-associated genes (Supplementary Table S1); MAF threshold 5%; variants validated by Sanger sequencing; cascade testing restricted to the two proband variants.
Genotyping Method: NGS targeted panel (Maxwell 16 DNA extraction, Agilent Alyssa analysis, Illumina Variant Interpreter, in-house pipeline) with Sanger validation; parental Sanger genotyping for the same two variants.
FunctionalAnalysis: None performed by the authors. They cite prior HeLa cell work showing the MYBPC3 c.1790G>A change causes exon 18 inclusion in the transcript and an almost undetectable 248 bp product.
Variant 1: PTPN11 NM_002834.3:c.1510A>G (p.Met504Val); heterozygous missense; de novo; classified pathogenic, explains Noonan syndrome
ClinVar: Not stated in the paper; verify the current record before submitting.
CAID: N/A
gnomAD: Not reported in the paper; I have not checked gnomAD for this variant.
Variant 2: MYBPC3 NM_000256.3:c.1790G>A (p.Arg597Gln); heterozygous missense; exon 18, last nucleotide of the exon, affecting a highly conserved residue and causing a splicing variation; inherited from the father
ClinVar: Not stated in the paper; authors note it is classified pathogenic/likely pathogenic for HCM in several genetic databases.
CAID: N/A
gnomAD: N/A
PMID: 32824488
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.

FamilyInfo: Family’s roots were traced to the German town of Leipzig in Saxony, from whence the original 11 siblings had immigrated to America around 1670. The following report is a 2011 updated pedigree on the previously reported Tisherman kindred. At the time of this study, 43/49 patients have undergone mutational analysis revealing the VHL familial mutation (Y112H) and 35/49 patients have clinical VHL manifestations. 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.

Central Nervous System Hemangioblastoma in a Pediatric Patient Associated With Von Hippel-Lindau Disease: A Case Report and Literature Review
PMID: 34109129
Gene: VHL
StandardizedReferenceSequence: NM_000551.3
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.
