Roger Colobran

The provided articles do not mention anyone named Roger Colobran. Instead, they detail the first documented case of a rare genetic disease, hereditary angioedema, being transmitted through the sperm of an anonymous donor at a fertility clinic in Catalonia, Spain. The discovery was made after an 18-year-old patient from Lleida experienced unexplained episodes of severe skin inflammation. Investigations by Hospital Vall d'Hebron in Barcelona and Hospital Universitario de Santa Maria de Lleida revealed the donor as the source. This case, published in the scientific journal Frontiers, is significant because it highlights a previously unknown risk associated with anonymous sperm donation and underscores the importance of thorough genetic screening of donors to prevent the transmission of rare hereditary diseases. Three people in Catalonia have been affected.
