Welcome to IthaMaps
IthaMaps is a global epidemiology database of heamoglobinopathies, illustrating published data on a dynamic global to regional map. Country-specific information on haemoglobinopathy-related policies, prevalence, incidence and overall disease burden is given, including relative allele frequencies of specific globin mutations in each country and/or region, dynamically linked to corresponding IthaGenes entries.
IthaMaps content was supported by partnership with the HVP Global Globin 2020 Challenge

Haemoglobinopathy-specific healthcare policy information for Bangladesh
Healthcare policy | Comment/Info | Reference | |
---|---|---|---|
Prevention programme: | Yes (National) | Screening services as part of the National Thalassemia Prevention Program | [PMID: 31941534] |
SCD newborn screening: | No | [PMID: 28521805] | |
Prenatal screening: | Yes (National) | At least three centres provide PND services. Practice of PND is low due to lack of knowledge of PND, lack of resources and the fact that it is not offered free of charge. | [PMID: 34271949] |
Antenatal screening: | No | [PMID: 25821805] | |
Haemoglobinopathies patient registry: | Yes (National) | Thalassemia Patient Registry [http://thalassemia.org.bd/] | |
Dedicated treatment centres: | Yes (National) | Few specialized thalassaemia care centres, most are in Dhaka city e.g., Bangladesh Thalassaemia Samity Hospital, Thalassemia Foundation Hospital | [PMID: 34271949] |
Blood transfusion availability: | Yes (National) | Barriers exist in collecting blood due to lack of support from organized donor’s clubs or NGOs, lack of awareness for voluntary blood donation. | [PMID: 34271949] |
Iron chelation availability: | Yes (Regional) | [PMID: 28521805] | |
MRI facilities: | No | ||
Patient associations: | Yes (National) | E.g.: Bangladesh Thalassaemia Samity; Bangladesh Thalassaemia Foundation; Lab One Foundation of Thalassaemia; Thalassaemia Welfare Centre. | |
Genetic counselling: | Yes (Regional) |

β-locus
CD 26 GAG>AAG [Glu>Lys] (HbE): 53.28 % (39.2 % – 80.44 %) | IVS I-5 (G>C): 34.1 % (15.11 % – 48.1 %) |
CD 30 (G>C) or IVS I (-1) AGG>ACG (Arg>Thr) (Hb Monroe): 3.5 % | CD 30 (A>C) or IVS I (-2) AGG>CGG [Arg>Arg]: 2.95 % |
Detailed mutation frequencies
Entry ID | Locus | Region | Ethnic Group | Population Type | Sample Size | Study period (from) | Study period (to) | Reference | Comments | |
---|---|---|---|---|---|---|---|---|---|---|
23594 | β-locus | Country-wide | Bangladeshi | Carriers and Patients | 237 | 2016 | 2019 | 33092414 | Frequencies are shown for beta-globin gene mutations and were calculated by Ithanet. Samples were collected from fetuses during prenatal diagnosis at the Dhaka Paediatric Neonatal & General Hospital, Lalmatia. The majority were carriers (~82%) of beta-globin gene mutations. | |
23595 | β-locus | Country-wide | Bangladeshi | Carriers | 225 | 2018 | 2019 | 31941534 | Frequencies are shown for beta-globin gene mutations and were calculated by Ithanet. Marriage-age participants (n=1877) from 10 different institutions (universities, medical colleges and business organizations) of Dhaka city. The majority of study subjects carrying beta alleles were carriers (95.3%). | |
23596 | β-locus | Chittagong | Bangladeshi | Patients | 256 | 2015 | 26402558 | Frequencies are shown for beta-globin gene mutations. Study samples were acquired from the Thalassaemia Welfare Centre and originated from different areas of Chittagong. |
