    Germline origins in the human F9 gene: frequent G:C→A:T mosaicism and increased mutations with advanced maternal age

      mutation

      Case#: HB348 (assumed male, Caucasian, 28 y/o)

      DiseaseAssertion: No disease assertion made

      FamilyInfo: Of the 30 families, germline or so- matic origins were found in 9 mothers, 5 maternal grandmothers, and 16 maternal grandfathers. For the 29 incomplete families, origins were found in 14 mothers, 5 maternal grandmothers, and 10 maternal grandfathers. Comparing the two family types shows no significant difference (P=0.29), suggesting that no major bias occurs in the analyses because of the inclusion of incomplete families
