WebA founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have: reduced genetic variation from the original population. a non-random sample of the genes in … WebApr 11, 2012 · Almost 70% of all carriers had the founder mutation D92Y ( 602690.0004) in SDHD; approximately 89% of all SDH mutation carriers had 1 of 6 Dutch founder mutations. The dominance of SDHD mutations was unique to the Netherlands, contrasting with the higher prevalence of SDHB mutations found elsewhere. REFERENCES

Four of the 5 families with the Leiden mutation had members who developed melanoma. In the fifth family, only pancreatic cancer segregated with mutation status. WebThe risk of developing a tumor depends on the sex of the parent who transmits the mutation: paragangliomas only arise upon paternal transmission. In this study, both the risk of paraganglioma and phaeochromocytoma formation, and the risk of developing associated symptoms were investigated in 243 family members with the SDHD.D92Y founder mutation. marianela ramsdell
