Researchers have identified candidate genes associated with albinism in Wels catfish, adding to the scientific understanding of pigmentation genetics across species.
A pale catfish became the subject of a genetic investigation. Scientists studying the Wels catfish — one of Europe's largest freshwater fish — have identified a set of candidate genes associated with albinism in the species, according to a report published via EurekAlert.
The Wels catfish (Silurus glanis) occasionally produces individuals with severely reduced pigmentation. Researchers used this natural variation as a starting point to examine which genes might be responsible, the report stated.
The study identified multiple candidate genes connected to pigmentation pathways. According to the researchers, several of these genes have known counterparts in pigmentation research across other vertebrate species, suggesting shared biological mechanisms that extend well beyond fish.
The findings contribute to a growing body of comparative genetics research. Scientists studying albinism in non-human species often surface gene variants and molecular pathways that later inform understanding of pigmentation conditions in humans, according to researchers in the field.
The source article did not detail the specific genes by name or describe the methodology in full. The complete findings are available through the linked research publication.
