Topic 4: Worm infestation causes Megaloblastosis by B12 Deficiency
Vitamin B 12 deficiency is an important cause of Megaloblastosis and develops in the vast majority of cases as a result of impaired vitamin B12 absorption.
Topic 5: Hereditary Retinoblastoma is transmitted as Autosomal Dominant
In hereditary retinoblastoma, a chromosome containing an allele of the Rb gene that has been deleted or inactivated by mutation is transmitted in a typical autosomal dominant fashion. All of the cells of the body of a person who has inherited this abnormality begin with only one normal copy of the Rb gene.

Topic 5: Iron deposition occurs in which organs predominantly in…….. Genetic Hemochromatosis
Hemochromatosis is a disorder of iron storage. It results in the deposition of excessive amounts of iron in parenchymal cells with eventual tissue damage and impaired function of organs, especially the liver, pancreas, heart, joints, and pituitary. Hereditary or genetic Hemochromatosis is most often caused by the inheritance of a mutant HFE gene, which is tightly linked to the HLA-A locus on chromosome 6p.
Below is the List for Latest and Important Topics for NEET DM Superspeciality Exams:
Topic 1: Tissue transglutaminase would be seen to generate antigenic epitopes in alpha-gliadin in Celiac disease.
Celiac disease is a common immune-mediated disease common with HLA DQ2 and HLA DQ8 Positivity. Here IgA antibodies are also found against reticulin which is found in the submucosal layer of the jejunum. There is a Presence of Antigliadin antibodies, Antireticulin antibodies, Anti transglutaminase antibodies, and Anti endomysial antibodies. Tissue transglutaminase would be seen to generate antigenic epitopes in alpha-gliadin in the Celiac sprue.
Topic 2: C282Y Mutations in the HFE gene are detected in patients with which Disease… Hemochromatosis
Hemochromatosis is most often caused by the inheritance of a mutant HFE gene, which is tightly linked to the HLA-A locus on chromosome 6p. Homozygous C282Y Mutations in the HFE gene are detected in many patients with the Hereditary Form of Disease. It is a common disorder of iron storage, in which an appropriate increase in intestinal iron absorption. It results in the deposition of excessive amounts of iron in parenchymal cells with eventual tissue damage and impaired function of organs, especially the liver, pancreas, heart, joints, and pituitary.
Topic 3: Vitamin B12 bound to IF is absorbed by… ileal mucosa.
Vitamin B 12 deficiency is an important cause of Megaloblastosis and develops in the vast majority of cases as a result of impaired vitamin B12 absorption. Dietary vitamin B12 is bound to intrinsic factor (IF) secreted by the stomach and vitamin B12 bound to IF is absorbed by ileal mucosa.
Topic 4: Beta 2-microglobulin is produced by ……B cells
It is a protein produced by B-cells; high concentrations in the blood are indicative of multiple myeloma.
Beta-2-Microglobulin is found in the serum of normal individuals and in the urine in elevated amounts in patients with Wilson disease, cadmium poisoning, and other conditions leading to renal tubular dysfunction.
Topic 5: Raised Arginase 1 Levels are seen in Patients with… which Cancer.
Hepatitis C can lead to the development of Hepatocellular Cancer. Raised Arginase 1 Levels are seen in Patients with Hepatocellular Cancer.
Topic 6: Hemangioblastomas are seen in association with … Von Hippel-Lindau syndrome
Hemangioblastoma is a vascular tumor of unknown histologic origin that frequently develops in the cerebellum of patients with von Hippel-Lindau syndrome. Renal cell carcinomas are also common in this disease. Von Hippel-Lindau syndrome is caused by autosomal dominant mutations of the VHL gene, a tumor suppressor gene.

Topic 15: Myoglobin is the Earliest Marker to Rise in Acute MI
Myoglobin is released into the blood within only a few hours of the onset of AMI. Although myoglobin is one of the first serum cardiac markers that rises above the normal range after AMI, it lacks cardiac specificity, and it is rapidly excreted in the urine, so that blood levels return to the normal range within 24 hours of the onset of infarction.
