Consanguineous relationships are those between blood relatives, typically first cousins. In the UK, cousin marriages are more common within certain South Asian communities. Around 55% of known consanguineous marriages in the UK are between people of Pakistani heritage.
Children of consanguineous relationships are at increased risk of genetic disorders and congenital abnormalities. Estimates indicate that there are around 20 births annually in Oldham affected by consanguinity-related disorders.
Oldham has a Genetics Outreach Service which aims to support individuals and families affected by autosomal recessive gene disorders which are more likely to occur within cousin marriages. More information about the service can be found here. A summary of the service evaluation can be found here.
