“…Campbell et al [13] [15]. Several studies have shown that the prevalence of the JAK2 V617F mutation in ET is ranging approximately from 23 to 69 % [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. In the present study, the frequency of JAK2 V617F mutation positive was 46 % in ET, which is consistent with the studies in the literatures.…”

“…We showed that significant increase only in the creatinine (p = 0.0001) and direct bilirubin levels (p = 0.032) in ET patients with JAK2 mutation. Compared with mutation-negative patients, those with the mutation-positive were older (57 ± 15) which was consistent with several studies, although our result was not statistically significant [1,2,13,16,18]. In contrast to some of the studies displayed no significance between gender and JAK2 gene mutation, our results showed male predominance (58 %) (p = 0.004).…”

“…Indeed, Ayad et al [4] in Egypt reported 81.4% positivity, whereas Benmoussa et al [5] in Morocco recorded 89.4% for the workforce of 246 and 88 cases of myeloproliferative disorders. Outside of Asian studies [16,17], the positivity proportions are identical to those of North Africa [4,5], the Western series reported a positivity rate of 95% during the Polycythemia Vera [18,19].…”

“…Especially the discovery of the mutation JAK2V617F [3] in polycythemia vera raises many questions. Few studies have been conducted in Africa [4,5] in this context. In Togo a preliminary study was done in 2011 on the biological profile including research in the JAK2V617F first 15 patients followed for myeloproliferative syndromes in which JAK2 mutation was investigated systematically.…”

“…Las mutaciones patogénicas en JAK2 exón 14, MPL exón 10 y CALR exón 9 se presentaron de manera excluyente en cada individuo. JAK2 V617F, fue la mutación más frecuente en 5 casos de PV y 2 casos en igualdad para TE y MFP, con frecuencias de presentación por debajo a las reportadas por otros países como Marruecos (18), Estados Unidos (14) y Argentina (19), pero mucho más alta comparada con el estudio local realizado en la ciudad de Bogotá por Solano et al ( 2012), en donde incluyeron 34 pacientes con NMPC BCR::ABL1 negativa, sólo a 8 (cinco con TE, dos con MFP y uno con PV) se les realizó análisis mutacional para JAK2 V617F, con un 100% de negatividad, resultados que llaman la atención teniendo en cuenta que esta mutación es la más frecuente en estas entidades, ante estos resultados, ellos concluyen que "No es posible analizar la presencia de las mutaciones tirosina-kinasas, ya que son herramientas de reciente ingreso al panel diagnóstico y cuyo impacto como factor pronóstico o terapéutico se encuentra en estudio" (6). Sin embargo, consideramos que estos resultados tal vez pudieron estar influenciados por la pequeña cantidad de pacientes analizados mutacionalmente (8/34) y por el tipo de NMPC elegida para dicho análisis (teniendo en cuenta que la mutación JAK2 V617F se presenta en el 95% de los pacientes con PV, creemos que el número de pacientes analizados mutacionalmente con PV debió ser mucho mayor).…”
