Diabetes Family History Genogram

A three-generation genogram illustrating the clustering of Type 2 diabetes within a family, including comorbid cardiovascular conditions. Paternal grandparents both had T2D, the father was diagnosed at 45, a paternal aunt has Type 1 diabetes, and the maternal grandmother had gestational diabetes. The index patient is a 35-year-old male recently identified as pre-diabetic. Lifestyle and occupational risk factors are documented throughout.

This 3-generation genogram maps 12 family members with birth years spanning from 1933 to 1994, comprising 6 males and 6 females (3 deceased). The genogram tracks 2 medical/psychological condition categories. The index patient is Kevin Meyers (b. 1991), software developer.

Across 3 generations, the Diabetes Family History family demonstrates hereditary risk patterns. The founding generation includes Harold, Dorothy, Eugene, with 4 members presenting health conditions.

Medical and psychological conditions are documented in 8 of 12 family members (67%). Diabetes appear in 7 members (Harold, Dorothy, Marlene...), affecting 3 females and 4 males. Cardiovascular conditions appear in 4 members (Harold, Dorothy, Eugene...), affecting 1 female and 3 males. Comorbidity is observed in 3 family members, with Harold presenting 2 concurrent condition categories. The multigenerational prevalence of diabetes suggests both genetic predisposition and possible environmental or behavioral transmission pathways.

From a genetic counseling perspective, this genogram provides critical risk stratification data. The clustering of diabetes and cardiovascular conditions across generations indicates heritable risk factors. Healthcare providers can use this multigenerational map to guide screening recommendations, inform preventive strategies, and counsel family members about their individualized risk profiles.
