Emm blood group full form

A 65-year-old man from Gujarat's Rajkot required blood to undergo a cardiac surgery last year. But the doctors were not able to determine the blood group of the patient. During the course of treatment, it was discovered that the patient had a rare blood type -- EMM negative. In general, there are four types of blood group -- A, B, O, or AB, which further consist of 42 types of systems, like A, B, O, Rh and Duffy. There are also 375 types of antigens in which EMM is high. Doctors were surprised to learn that he had a unique blood group and referred him to Ahmedabad. But there too, the doctors couldn't find the life saving fluid matching to his blood group. The lab testing of the blood sample collected from his body was quite different and strange from the existing groups. The sample was sent to a lab in New York for testing. It took a year for the researchers to come to the conclusion that the blood group was AB+ blood group with EMM negative frequency. The patient died a natural death earlier this year. What is EMM negative? The Rajkot man is said to be the first person in India and 10th in the world with an EMM blood group. As EMM level is low in blood, the International Society of Blood Transfusion (ISBT) named it EMM negative. The blood group has been given symbol ISBTO42. EMM negative people can't donate People with EMM negative blood group can't donate blood to anyone. They neither can accept blood from anyone. Experts say that if a person even receives blood from a p...

Extramedullary myeloma (EMM) is defined by the presence of plasma cells (PCs) outside the bone marrow in a patient with multiple myeloma (MM). Using sensitive imaging techniques including magnetic resonance imaging and positron emission tomography/computed tomography, EMM may be found in up to 30% of MM patients across the overall disease course. The molecular mechanisms underlying the hematogenous spread of PCs outside the bone marrow are only partially known and involve hypoxia and an altered expression of adhesion molecules. Extramedullary disease is associated with adverse prognostic factors (ie, high lactate dehydrogenase level, 17p deletion, and high-risk gene expression profile). The prognosis of EMM is poor, and the median overall survival of patients who experience an extramedullary relapse is <6 months. The adverse prognosis is less pronounced in patients with bone-related plasmacytomas than in those with hematogenous EMM. EMM patients should be considered as having high-risk myeloma and treated accordingly. However, EMM clinical situations are extraordinarily heterogeneous, and their management is particularly challenging. In the present review, a case-and-comment format is used to describe our approach to the management of EMM. EMM entities . Definition . Clinical presentation . Bone-related plasmacytomas Plasmacytomas developed from the bone, arising in continuity with the bone marrow. Tumor masses affecting the axial skeleton: ribs, vertebrae, skull, sternum,...

The Emm red blood cell antigen is assigned number 901008 in the International Society of Blood Transfusion (ISBY) 901 series of high incidence antigens. Emm has been designated the 42nd blood group system. Rare individuals have an Emm- phenotype due to homozygous loss-of-function mutations in the PIGG gene. These individuals often have naturally occurring anti-Emm antibodies that are identified during routine blood type and crossing. These antibodies have the potential to cause acute hemolytic transfusion reactions (summary by Duval, R., Nicolas, G., Willemetz, A., Murakami, Y.

Blood Group I System i blood group, individuals of which have a linear poly-N-acetyllactosamine without branching, is caused by inactivation of exon C or the common exon. From: Comprehensive Glycoscience, 2007 Related terms: • Coagulopathy • Blood Stasis • Platelet • Minor Surgery • Family History • Thromboembolism • Birth Weight Beth H. Shaz MD, in Transfusion Medicine and Hemostasis, 2009 Publisher Summary This chapter gives a review of the Lewis, I and P blood group systems. The antigens in the Lewis blood group systems are composed of terminal carbohydrate moieties added to protein or lipid backbones in a configuration similar to that of the ABO antigens. The Lewis blood group antigens Le a and Le b are synthesized by two independent fucosyltransferases and the corresponding antibodies are usually not of clinical significance. The Lewis antigens are not intrinsic to the red blood cell membrane but are synthesized by intestinal epithelial cells, circulate in the plasma either free or bound to lipoproteins and are then passively absorbed onto the RBC membrane. Antibodies to the Lewis antigens are primarily IgM, naturally occurring and not usually clinically significant except in rare case of hemolytic transfusion reactions. The P and GLOB blood group systems are discussed and the P antigens are usually defined by sugars added to precursor glycoshingolipids and their synthesis occurs by sequential addition of monosaccharides to the precursor molecule by glycosyltransferas...

Emm is a high incidence red cell antigen with eight previously reported Emm− probands. Anti-Emm appears to be naturally occurring yet responsible for a clinically significant acute hemolytic transfusion reaction. Previous work suggests that Emm is located on a GPI-anchored protein, but the antigenic epitope and genetic basis have been elusive. We investigated samples from a South Asian Indian family with two Emm− brothers by whole genome sequencing (WGS). Additionally, samples from four unrelated Emm− individuals were investigated for variants in the candidate gene. Filtering for homozygous variants found in the Emm− brothers and by gnomAD frequency of The aim of this study was to improve knowledge of the mutational spectrum causing tuberous sclerosis complex (TSC) in a sample of Mexican patients, given the limited information available regarding this disease in Mexico and Latin America. Four different molecular techniques were implemented to identify from single nucleotide variants to large rearrangements in the TSC1 and TSC2 genes of 66 unrelated Mexican-descent patients that clinically fulfilled the criteria for a definitive TSC diagnosis. The mutation detection rate was 94%, TSC2 pathogenic variants (PV) prevailed over TSC1 PV (77% vs. 23%) and a recurrent mutation site (hotspot) was observed in TSC1 exon 15. Interestingly, 40% of the identified mutations had not been previously reported. The wide range of novels PV made it difficult to establish any genotype-phenotype...

EMM Negative Blood Group: India's first unique blood group, EMM Negative, has been detected in a 65-year-old man in Gujarat. EMM Negative Blood Group is the world's rarest blood group. The Gujarat man is the world's tenth person with the world's most rare blood type. The man, who suffers from a heart disease, was found to have the world's rarest blood group EMM Negative. In general, there are four different blood types- A, B, O or AB. However, the EMM Negative blood group cannot be classified into any of these regular blood types. The human body contains a total of 42 different types of blood systems including A, B, O, Rh and Duffy. There are about 375 different types of antigens in which EMM is in high amounts. India's first unique blood group: EMM Negative Blood Group • So far, there were only 9 people in the world with such rarest blood group, but now, a 65-year-old man from Gujarat's Rajkot has been identified with the said blood group. • The 65-year-old man had been undergoing treatment in Ahmedabad after suffering a heart attack. • He was in need of blood for his heart surgery but when his blood type was not found in Ahmedabad's Prathama laboratory, his blood samples were sent to the blood donation centre in Surat. • Further testing revealed that the man has the world's most rarest blood type. Before him, there were only 9 people with the world's most rare blood type. • The International Society of Blood Transfusion (ISBT) has designated the blood type as EMM negativ...
