Kawasaki disease (KD) is a rare acute systemic vasculitis syndrome that typically affects young children and can cause coronary artery aneurysm potentially followed by cardiovascular sequelae. KD is a worldwide illness and the leading cause of acquired heart disease among children in developed countries. While the exact etiology of Kawasaki disease remains unknown there is growing evidence to suggest the contribution of genetic factors to the disease. The leading theory to explain KD pathogenesis suggests the disease is triggered by an infection, which subsequently initiates an abnormal immune response in genetically susceptible individuals. To identify the genetic factors that may have a role in KD susceptibility we conducted whole-exome sequencing of 76 patients from all over the world. The association analysis identified the suggestive association of four common SNPs located in CCHCR1 and five rare coding variants in the gene GTF3C5. These results provide genetic variants potentially involved in the development of KD, but they need to be validated in larger cohorts and new investigations appear necessary to gain further insights into this disorder.
La malattia di Kawasaki (KD) è una rara sindrome di vasculite sistemica acuta che colpisce tipicamente i bambini e può portare ad un aneurisma delle arterie coronarie, potenzialmente seguito da sequelae cardiovascolari. La KD è una malattia diffusa in tutto il mondo ed è la principale causa di malattia cardiaca acquisita nei bambini in paesi sviluppati. Sebbene l'eziologia esatta della malattia di Kawasaki rimanga sconosciuta, ci sono prove sempre più evidenti che suggeriscono il contributo di fattori genetici alla malattia. La teoria principale per spiegare la patogenesi della KD suggerisce che la malattia sia innescata da un'infezione, seguita da una risposta immunitaria anormale in individui geneticamente predisposti. Con l’obbiettivo di identificare i fattori genetici alla base della predisposizione alla KD, abbiamo condotto il sequenziamento dell’esoma completo di 76 pazienti provenienti da tutto il mondo. L'analisi di associazione ha identificato l'associazione suggestiva di quattro SNP comuni nel gene CCHCR1 e cinque varianti rare codificanti nel gene GTF3C5. Questo studio propone alcune varianti genetiche potenzialmente coinvolte nello sviluppo della KD. I risultati ottenuti necessitano di essere confermati in coorti più ampie ed ulteriori approfondimenti sono fondamentali per comprendere a pieno la KD.

Abstract
Kawasaki disease (KD) is a rare acute systemic vasculitis syndrome that typically affects young children and can cause coronary artery aneurysm potentially followed by cardiovascular sequelae. KD is a worldwide illness and the leading cause of acquired heart disease among children in developed countries. While the exact etiology of Kawasaki disease remains unknown there is growing evidence to suggest the contribution of genetic factors to the disease. The leading theory to explain KD pathogenesis suggests the disease is triggered by an infection, which subsequently initiates an abnormal immune response in genetically susceptible individuals. To identify the genetic factors that may have a role in KD susceptibility we conducted whole-exome sequencing of 76 patients from all over the world. The association analysis identified the suggestive association of four common SNPs located in CCHCR1 and five rare coding variants in the gene GTF3C5. These results provide genetic variants potentially involved in the development of KD, but they need to be validated in larger cohorts and new investigations appear necessary to gain further insights into this disorder.File | Dimensione | Formato | |
