Type 2 diabetes diagnoses among Black and Asian men delayed due to hidden genetic risk

Type 2 Diabetes Diagnoses Delayed in Black and Asian Men Due to Hidden Genetic Risk

A hidden genetic variant found in Black and Asian men could cause delays in them being diagnosed with type 2 diabetes, new evidence has indicated.

A genetic variant known as G6PD deficiency was detected in around one in seven Black and one in 63 South Asian men in the UK, according to a recent study.

Previous research has found that men with the genetic disorder are more likely to be diagnosed with type 2 diabetes four years later compared to those without G6PD deficiency.

“Our findings highlight the urgent need for changes to testing practices to tackle health inequalities,” said Lead author Professor Inês Barroso.
