Deletions of one to three normal [alpha]-globin genes causes an increasing reduction in [alpha]-globin chain synthesis in carriers of [alpha]+ Thalassaemia (-[alpha]/[alpha][alpha], --/[alpha][alpha] or -[alpha]/-[alpha]), [alpha]0 thalassaemia (-[alpha]/[alpha] [alpha] o r - [alpha]/-[alpha]), [alpha] 0 thalassaemia (--/[alpha][alpha]) and haemoglobin H disease (--/-[alpha]).1-3 Commonest deletional ATs found in Pakistani population are -[alpha] 3.7 with a frequency of 8.3% and the rare forms include -[alpha] 4.2 (0.2%) and [alpha][alpha][alpha] anti-3.7(0.9%).4 Beta Thalassaemia (BT) results in reduced synthesis ([beta]+) or complete su ppression ([beta]0) of [beta]-globin chain synthesis.
Summary: Bengaluru (Karnataka), Apr 19 (ANI): BJP's Karnataka unit on Thursday wrote to the Election Commission over alleged "mass indiscriminate
deletion of voters' names from the voters list" in the state.
Whole blood samples processed with standard phenol chloroform protocol for DNA isolation were genotyped using multiplex PCR approach for simultaneous identification of GSTM1 and GSTT1
deletions. The genotype frequency obtained for patients was compared to controls using odds ratio and chi-square.
The majority of DMD cases are caused by gene
deletion or duplication in single or multiple exons, which account for about 65% and 5-8%, respectively.[9] The remaining cases are attributable to point mutations, splicing mutation, and small
deletions and insertions.[3],[9] Previous reports indicate that approximately 70% of these lethal mutations are inherited from a carrier mother,[2] whereas 30% of the mutation are de novo .[10] To date, no effective therapy is widely available for DMD/BMD patients.
The "pure"
deletion of 11p15 region with no other chromosomal imbalance is extremely uncommon.
Our patient with hyperglycemia and dysmorphic features had a
deletion of 7.23 Mb comprising the region 7p13-p12.1, with involvement of 39 Online Mendelian Inheritance in Man genes, including glucokinase associated with maturity-onset diabetes of the young, CCM2 associated with type 2 cerebral cavernous malformations, insulin-like growth factors binding protein-3 associated with decreased postnatal growth, and oxoglutarate dehydrogenase associated with alpha-ketoglutarate dehydrogenase deficiency (short stature, hypotonia, cognitive impairment, and movement abnormalities).
In this study, the co-inheritance of [beta]-thal alleles with common [alpha]-globin gene
deletions was evaluated in asymptomatic carriers of [beta]-thal in an Iranian population.
Chromosomal microdeletions and duplications are one of the major causes of congenital malformations and developmental delay.Lately by the effect of array-CGH,many new syndromes are defined in patients with congenital malformations and developmental delay.Xp21 contiguous gene
deletion syndrome is one of the rare microdeletion syndromes.This syndrome is characterized by developmental delay,congenital adrenal hypoplasia, DuchenneMuscularDystrophy (DMD) and glycerol kinase deficiency.
Chair Bautista already believed that there would be no problem or 'tight timelines' to make such
deletion because as it appears, Chair Bautista was confident that all the ballots would be printed on time and that Comelec had all the time to make such corrections or
deletions, the motion added.
Since definitive exclusion of [alpha]-thalassaemia can only be obtained through molecular characterisation of the [alpha]-globin gene, the most logical diagnostic approach for unexplained microcytosis would be to use polymerase chain reaction (PCR) analysis to detect the common a-globin gene
deletions. In this study we employed a multiplex PCR assay designed to detect the seven most common [alpha]-thalassaemia
deletions.
Previous maps of human genetic diversity have usually not marked the yawning chasms left by
deletions or the new territory created by duplications.
Various studies from India and abroad have documented
deletions in the main "hot spot" region between exons 45-53 in majority of cases.
