Whole genome sequencing (WGS) has the potential to detect different types of genetic variation. Please indicate which one of the genetic variants would remain undetected via this test.
Copy number variants
Epigenetic variants
Mitochondrial sequence variants
Non-coding variants
Single nucleotide variants
A 35-year-old woman diagnosed with high-grade breast cancer at 33 years is attending the oncology clinic for counselling and consideration of genetic testing. Her paternal aunt was diagnosed with breast cancer at 39 years and her paternal uncle died at 55 years due to a brain tumour. She has a 6 year old daughter recently diagnosed with a soft tissue sarcoma.
Which of the following genes would you sequence as a priority?
BRCA1
BRCA2
TP53
PTEN
PALB2
A 23-year-old male patient presents with a 1-year history of developing several smooth firm skin coloured papules around his nails and associated with a longitudinal groove on affected nails. He had a history of hypopigmented areas on his torso and also a history of small pink red papules over his cheeks and nose since childhood. He also had a background history of epilepsy and has a mild learning disability. Which is the most likely unifying diagnosis?
Birt-Hogg-Dube
Familial leiomyomas
Cowden syndrome
Tuberous sclerosis
Muir-Torre syndrome
A 31-year-old woman was seen in the genetics clinic shortly after delivery of her baby. Antenatally there was cystic hygroma, and amniocentesis had identified a normal male karyotype. Her baby was found to have lymphoedema of the feet at birth. The woman had a history of learning difficulties and had pulmonary stenosis under Cardiology review. What is the most likely diagnosis in the family?
Emberger syndrome
Hennekam syndrome
Lymphoedema distichiasis syndrome
Noonan syndrome
Turner syndrome
A 36-year-old woman with colorectal cancer has consented to undergo whole genome sequencing of her tumour DNA and germline DNA. At present, she has only consented to receive information relevant to her current diagnosis. Which of the following would be most appropriate to seek from her germline DNA for variant interpretation with a view to reporting back to the patient?
A missense variant in the gene BRCA1
A nonsense mutation in MSH2, a DNA mis-match repair gene
A single nonsense sequence variant in the gene MUTYH which in biallelic form causes multiple colorectal adenomas
A single nucleotide deletion in the gene LDLR, which causes familial hypercholesterolaemia
The presence of the BRAF V600E mutation
A 22-year-old man is seen in your clinic. From birth he had hypertrophy of his left leg with an associated epidermal naevus, lipomas and scoliosis (CLOVES). You wish to arrange genetic testing to confirm the diagnosis. What is the most appropriate genetic test to arrange?
A blood test for a panel of genes associated with lymphoedema
A blood test for chromosome analysis (karyotype)
A saliva sample for a panel of genes associated with lymphoedema
A skin biopsy from the right leg sent for testing of a panel of genes in the PI3K/AKT/mTOR pathway
A skin biopsy from the left leg sent for testing of a panel of genes in the PI3K/AKT/mTOR pathway
A 36-year-old male patient presents with a several years history of developing multiple yellow white papules on his neck, upper trunk and mid face. He has a family history of renal cell carcinoma and a personal history of a previous pneumothorax. What is the most likely underlying unifying diagnosis?
Familial leiomyomas
Cowden syndrome
Birt-Hogg-Dube
Tuberous sclerosis
Muir-Torre syndrome
A 37-year-old women with personal and family history of breast cancer underwent gene panel testing for suspected hereditary breast cancer. Her test identified a missense mutation in PALB2 gene. Which of the following information would be useful for interpretation of her test result?
In silico prediction analysis for the effect of the amino acid change to the protein product
Genetic testing in other affected relatives with breast cancer for the detected PALB2 mutation
Conservation data for the affected amino acid in other species
Assessment of the PALB2 mutation frequency in other affected and non-affected cohorts
All of the above.
Which of the following statements is true regarding panel testing in hereditary breast and ovarian cancer?
Panel tests typically identify genetic causes in >30% of BRCA1/2-negative families
The frequency of variants of uncertain significance (VUS) in panel tests is lower than single gene tests
There is no limit to the number of genes that can be put on a panel.
The absence of a pathogenic variant excludes the presence of familial and/or other inherited susceptibility factors.
Panel testing can be offered without genetic counselling on possible outcomes and implications to at-risk relatives.
A 36-year-old female patient was initially referred to the breast clinic following the development of a new breast lump. Following investigation in addition to bilateral fibrocystic disease she was found to have a suspicious breast lesion, which on biopsy was a malignant tumour. She described a several years’ history of the development of thickened papules around her nose and ears and also scaly red lesions on her bilateral palms and she was referred for dermatological assessment. Which is the most likely unifying diagnosis?
Birt-Hogg-Dube
Bazex syndrome
Cowden syndrome
CYLD cutaneous syndrome
Muir-Torre syndrome
