Abstract
A linkage and association analysis was made on 14 Italian families with recurrent migraine. We analyzed five chromosomal regions surrounding the candidate genes 5HT1D (1p36.3–34.3), 5HT1B (6q13), 5HT2A (13q14–21), 5HT transporter (17q11.2–12), CACNLB1 (17q11.2–22) and FHM (19p13), using 29 DNA polymorphic markers. All two-point lod scores were negative, and the x2 sib-pair analyses were not significant, thus indicating the probable exclusion of these regions as sites of migraine genes in our population. È stata condotta un'analisi di linkage ed associazione su 14 famiglie italiane con ricorrenza di emicrania. Abbiamo analizzato cinque regioni cromosomiche attorno ai geni candidati 5HT1D (1p36.3-34.3), 5HT1B (6q13), 5HT2A (13q14-21), 5HT transporter (17q11.2-12), CACNLB1 (17q11.2-22) e FHM (19p13), usando 29 marcatori polimorfici del DNA. Tutti i valori dei lod-score a due punti erano negatitivi, i x2 della sib-pair analysis non erano significativi, escludendo così la presenza di geni per l'emicrania nella popolazione in esame nelle regioni analizzate.Keywords
