Summary

Story summary

Harvard Medical School researchers found that clonal expansions in sperm are common and linked to various genetic diseases.
The study shows how these mutations can confer advantages to sperm stem cells while potentially causing severe disorders in offspring.
University of Exeter researchers identified TMEM167A gene mutations as a cause of a rare neonatal diabetes form, affecting insulin production and linked to neurological disorders.
