Q1: A 16-year-old male presents with tall stature, small testes,
gynecomastia, and learning difficulties. What is the most likely
diagnosis?
A) Turner Syndrome
B) Klinefelter Syndrome
C) Marfan Syndrome
D) Cystic Fibrosis
Correct ,,,,answer,,,: B
Rationale: Klinefelter syndrome (XXY) is a chromosomal disorder in
males characterized by an extra X chromosome. Clinical features
include tall stature, small firm testes, gynecomastia, and learning
disabilities. The condition affects approximately 1 in 500-1000 males .
Q2: A 25-year-old female presents with short stature, webbed neck,
and primary amenorrhea. Which chromosomal abnormality is most
likely?
A) Trisomy 21
,B) Klinefelter Syndrome
C) Turner Syndrome
D) Down Syndrome
Correct ,,,,answer,,,: C
Rationale: Turner Syndrome (45, XO) is a chromosomal disorder in
females characterized by a missing or deformed X chromosome. Classic
features include short stature, webbed neck, right hemisphere
dysfunction, hearing loss, ear infections, and language/articulation
disorders. Turner syndrome occurs in approximately 1 in 2500 female
births .
Q3: Which genetic disorder affects the pancreas and causes
secretions into the lungs?
A) Sickle Cell Anemia
B) Cystic Fibrosis
C) Huntington's Disease
D) Hemophilia
Correct ,,,,answer,,,: B
Rationale: Cystic fibrosis is an autosomal recessive disorder caused by
mutations in the CFTR gene, affecting chloride transport across epithelial
cells. The condition affects the pancreas, causing thick secretions that
obstruct pancreatic ducts, and also affects the lungs with thick mucus
accumulation .
,Q4: What is beta thalassemia?
A) A condition of excessive iron absorption
B) A condition in which the synthesis of beta globin chains is reduced or
absent
C) A condition of increased red blood cell production
D) A viral infection of the bone marrow
Correct ,,,,answer,,,: B
Rationale: Beta thalassemia is a genetic disorder characterized by
reduced or absent synthesis of beta globin chains, which are essential
components of adult hemoglobin. This results in ineffective
erythropoiesis, chronic anemia, and potential iron overload from
transfusion therapy .
Q5: What is the inheritance pattern of osteogenesis imperfecta?
A) Autosomal recessive
B) Autosomal dominant
C) X-linked recessive
D) Mitochondrial
Correct ,,,,answer,,,: B
Rationale: Osteogenesis imperfecta is most commonly inherited in an
autosomal dominant pattern. The condition results from mutations in
genes encoding type I collagen, leading to brittle bones that fracture
easily.
, Q6: What is the underlying genetic mechanism in alpha thalassemia?
A) Deletion or dysfunction of alpha globin genes
B) Deletion or dysfunction of beta globin genes
C) Mutation in the CFTR gene
D) Extra X chromosome
Correct ,,,,answer,,,: A
Rationale: Alpha thalassemia is caused by deletions or dysfunction of
the alpha globin genes on chromosome 16. The severity depends on the
number of affected alpha globin genes. This is a common genetic
disorder affecting hemoglobin synthesis .
Q7: A newborn exhibits a distinctive "frog-leg" posture, and
radiographs show multiple fractures. What is the most likely
diagnosis?
A) Osteogenesis Imperfecta
B) Marfan Syndrome
C) Ehlers-Danlos Syndrome
D) Congenital Hypothyroidism
Correct ,,,,answer,,,: A
Rationale: Osteogenesis imperfecta Type II is the most severe form,
often presenting prenatally or at birth with multiple fractures, bowing of
long bones, and a characteristic "frog-leg" posture. The condition is often
fatal in the neonatal period.
