10/22/MClinical, geneticPartial deletion, protein truncating mutation++++−
PatientID: 10
KindredID: 10
Case: M, 22Y0M, Caucasian
DiseaseAssertion: VHL
FamilyInfo: Positive family history.
CohortInfo: Case series of 14 patients with definite or presumed von Hippel-Lindau disease and retinal vascular proliferation.
CasePresentingHPOs: HP:0002011, HP:0001732, HP:0007850, HP:0012210, HP:0009711 (Morphological central nervous system abnormality, abnormality of the pancreas, retinal vascular proliferation, abnormal renal morphology, retinal capillary hemangioma)
CaseHPOFreeText: At age 12, his left eye had a large juxtapapillary vascular complex extending from the nerve along the superior arcade that was associated with dense fibrovascular tissue. During the next 29 months, this fibrovascular complex enlarged, extending into the center of the macula and causing a decrease in visual acuity to 20/80. The patient underwent pars plana vitrectomy and membrane peel. When the patient was reexamined 7 years after his surgery, there was no recurrence of the lesion. In the patient's contralateral right eye, 3 typical peripheral RCHs were observed during this 7-year follow-up. At age 14 years, he was also noted to have a small patch of superficial retinal vessels in the inferior retinal quadrant near the equator of the right eye that resembled an arteriovenous anastomosis.

DICER1 Syndrome
GeneName: DICER1 PMID: 28323992 PMCID: PMC5443331 *No HGNCID found Inheritance pattern: autosomal-dominant Disease Entity: multinodular goiter and thyroid cancer Mutation: Germline Zygosity: not listed Variant: c.3726C>A; p.Tyr1242a, c.3675C>G; p.Tyr1225a Family Information: 145 individuals with DICER1 germline mutations from 48 family controls (135 individuals) that lacked the DICER1 mutation Case: male and female carriers as well as family members were studied. Ages: 20, 30, and 40 for both populations (DICER1 carriers were significantly younger than controls}. Population from Great Britain, UK, and USA (no significant difference between race, ethnicity, or sex found). CasePresentingHPOs: no previous therapeutic radiation or chemotherapy. Thyroid cancer or MNG diagnoses were likely reported with the DICER1 mutation CasePreviousTesting: Sequencing performed with Sanger or next-generation sequencing assays. DICER1 carriers underwent testing to obtain thyroid-stimulating hormone, thyroxine, thyroxine-binding globulin, and serum albumin levels as well as medical history and physical examinations (+thyroid palpation). Participants were also given thyroid US examinations. gnomAD: n/a Mutation Type: missense

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).
