	Original Article
		For confirmation, his blood specimen was air-shipped to Bombay, where detailed studies revealed the presence of depressed A antigens on his red cells that were detectable with variable strength with anti-A+B reagents prepared from group O individuals.
		Anti-H reagents were from locally detected cases of Bombay phenotype, immunized chicken, and lectin extracted from the seeds of Ulex europaeus anti-I (Steph) and anti-i (Ziag) from P Issitt, USA.
		The Bombay phenotype is characterized by group O which lacks H antigen on red cells and by the presence of anti-H along with anti-A and anti-B in the serum.

		Bombay Phenotype: In rare situations though, the O blood type of the child is not based on the phenotype/genotype of the parents.
		The Bombay phenotype individuals do have ABO genes on chromosome 9, that can be passed to future generations, even though these genes are not expressed in their own body.
		What causes Bombay Phenotype: The predominant cause of the Bombay phenotype is a mutation in the H gene on chromosome 19 that causes a non functional H glycosyl transferase to be produced.

		Another possible explanation is that the child or parent who tests as type O has the very rare Bombay phenotype: they have inherited two recessive alleles of the H gene, (their blood group is O
		The rare individuals with Bombay phenotype do not express H substance on their red blood cells and therefore do not bind A or B antigens.
		Instead, they produce antibodies to H substance (which is present on all red cells except those of hh phenotype) as well as to both A and B antigens and are therefore compatible only with other hh donors.

	Modern Human Variation: Bombay Phenotype (Site not responding. Last check: 2007-10-24)
		It is important to be cautious in predicting the ABO blood type of children based on the phenotypes of their parents.
		This is due to the fact that a third antigen (H) on the surface of red cells can prevent the expected ABO blood type from occurring.
		The result is an O phenotype by default since a lack of A and B antigens is the O type.

	The Hh blood group
		H antigen deficiency is known as the "Bombay phenotype" (h/h, also known as Oh) and is found in 1 of 10,000 individuals in India and 1 in a million people in Europe.
		Both the classical Bombay phenotype and a new variant type of partial H deficiency was seen in the islanders (4).
		The classical Bombay phenotype is caused by a Tyr316Ter mutation in the coding region of FUT1 (1, 8).

	The ABO Blood Group System (Site not responding. Last check: 2007-10-24)
		The Bombay blood group is a rare group except in parts of India where a frequency of 1 in 7,600 has been observed.
		The cause of the Bombay phenotype is, predominately, mutation in the H gene on chromosome 19 that causes a non functional H glycosyl transferase to be produced.
		The probable cause of the Para Bombay phenotype is a mutation in the H transferase gene on chromosome 19 which produces only a very weakly acting H glycosyl transferase.

	Hh - Blood Groups - SCARF Exchange
		Although the Bombay phenotype is extremely rare in most populations, a number of examples have been found in India over the years.
		Early suggestions were that this type was due to a new allele at the ABO locus, but others suggested an inhibitor gene and finally the possibility of a genetically independent but related gene.
		We now know that the Bombay phenotype is due to a recessive gene at the H locus; ie.

	Non-conforming Blood Types
		If you lack the H antigen, then you have the Bombay phenotype, and this would explain why you and your brother don't express the A or B anitgen which you should have inherited from your father.
		If your are a Bombay phenotype, you should store some of your own blood for a possible future transfusion.
		The fact that your daughter is Rh(-), means that she inherited the recessive Rh(-) gene from both you and your husband.

	Re: Can a Caucasian have Bombay blood?
		The bombay phenotype is characterized by mutations in fucosyltransferase.
		Therefore a person with Bombay has the phenotype of O blood even though genetically they might have a different blood type.
		Also the bombay phenotype is one of many elements of Rambam-Hasharom which is a genetic syndrome also characterized by mental retardation.

	MCDB-Homework #2 Discussion
		Comment: For #5, I suppose that we assume individuals with the hh allele display a pheonotype that is considered to be type O. From the parents, there is no way that a child can be a true type O (H-IoIo).
		Comment: ON question #2, there are two possible outcomes of phenotypic ratios depending on the genotype of the fl used from the F1 progeny..
		ABO blood-type is an example of multiple alleles, where A and B are codominant with each other, but both are dominant to O. Be careful about the epistatic Bombay phenotype from hh.

		These individuals with the so-called Bombay phenotype are recognized by the presence of anti-H in the serum, in addition to anti-A and anti-B, as in type O persons.
		(1982) expected a high incidence of H-deficient phenotypes among the half-million people living on Reunion Island (in the Indian Ocean east of Madagascar), since most of the cases of the Bombay phenotype published by French teams of Salmon and others traced their ancestry to this small island.
		On the basis of the Oriol model, 2 main types of recessive H-deficient red cell phenotypes are recognized: (1) the nonsecretor classic Bombay type (h/h, se/se) with H-deficiency of both red cells and saliva, and (2) the secretor Bombay type (h/h, Se/-) with normal ABH in secretions but H-deficiency in red cells.

		When this Blood group was first encountered, it was found not to be of either group A or B and so was thought to be of Group O. But on further test, it didnot match even for O-ve or O+ve because of the absence of Antigen 'h'.
		It is called Bombay group because, it was first discovered in Bombay.
		Given that this condition is very rare to begin with, any person with this blood group, who needs an urgent blood transfusion, may be simply out of luck, as it would be quite unlikely that any blood bank would have any in stock.

		Because the h gene is very rare, Bombays often result from consanguineous matings in which parents are blood relatives (e.g., first cousins).
		Their red cells lack ABH antigens and their sera contain anti-A and anti-B and anti-H. The anti-H would not be detected in the ABO group but would be detectable in pretransfusion tests, e.g., their sera would agglutinate group O screen cells and group O donor cells, which have the H antigen.
		Significance in blood transfusion: Bombay people would be incompatible when crossmatched with red cells of all normal ABO groups (groups O, A, B and AB).

		(1982) presented evidence that the fucosyltransferase of epithelial origin, coded by the Se gene, is able to transform both type 1 and type 2 natural substrate, whereas the enzyme of mesodermal origin, coded by the H gene (mutant in the Bombay phenotype), works preferentially on type 2 natural substrate.
