ABSTRACT

OBJECTIVE:

To document the existence and clinical characteristics of three large families with multigenerational inheritance of early-onset type 2 diabetes in Jamaica.

METHODS:

Three probands from large families with multigenerational inheritance of early-onset type 2 diabetes in at least three generations were detected at the University Hospital of the West Indies in Jamaica. Each proband at the time of diagnosis was < 25 years of age, was lean, and did not require insulin therapy. Clinical, metabolic, and genetic assessments were undertaken to profile the diabetes in the three families.

RESULTS:

Three pedigrees-BK, SU, and CA-consisting of 38, 48, and 113 members, respectively, with multigenerational inheritance of early-onset type 2 diabetes in at least three generations, were investigated. The mean age at diagnosis of the three pedigrees was 31.5 ± 2.9 years, with 10 persons detected below 25 years of age. Findings suggestive of overweight, insulin resistance, low insulin secretion, dyslipidemia, and mild intra-abdominal obesity were present. Islet cell antibodies and sequence variants in MODY1 to -6 genes were absent.

CONCLUSIONS:

Large families demonstrating multigenerational inheritance of diabetes and other characteristics consistent with early-onset type 2 diabetes are present in the Jamaican population.
RESUMEN

OBJETIVO:

Documentar la presencia de herencia multigeneracional de la diabetes de tipo II de inicio temprano en tres familias jamaiquinas grandes y describir sus características clínicas.

MÉTODOS:

En el Hospital Universitario de West Indies en Jamaica, se detectaron tres probandos de familias grandes en las que se observó herencia multigeneracional de la diabetes tipo 2 de inicio temprano en al menos tres generaciones. Al momento del diagnóstico, cada probando tenía # 25 años de edad, era delgado y no necesitó insulinoterapia. Se emprendieron estudios clínicos, metabólicos y genéticos con el fin de determinar las características particulares de la diabetes que presentan estas tres familias.

RESULTADOS:

Se investigaron tres árboles genealógicos -BK, SU y CA- conformados por 38, 48 y 113 miembros, respectivamente. Cada árbol presentaba herencia multigeneracional de diabetes tipo 2 de inicio temprano en al menos tres generaciones. En los tres árboles genealógicos, la media de la edad al momento del diagnóstico fue de 31,5 ± 2,9 años y 10 personas tenían menos de 25 años. Se observaron signos indicativos de sobrepeso, resistencia insulínica, baja secreción de insulina, dislipidemia y obesidad intrabdominal leve. No se hallaron anticuerpos contra las células de los islotes ni variantes en la secuencia de los genes MODY1 a MODY6.

CONCLUSIONES:

Algunas familias grandes de la población jamaiquina presentan herencia multigeneracional de la diabetes y otras características indicativas de diabetes tipo 2 de inicio temprano.
