About this episode

This episode discusses a new international case series on D-bifunctional protein deficiency, highlighting the possibility of survival into adolescence and adulthood.

A new international case series revisits the natural history of D-bifunctional protein deficiency, showing that survival into adolescence and adulthood is possible and that normal VLCFA levels do not exclude the diagnosis. Dr James Nurse speaks with Dr Unai Díaz-Moreno and Dr Spyros Batzios about expanding phenotypes, genotype–phenotype correlations, and the growing role of early genetic diagnosis.
