The aim of this study was to make a characterization of the communication in a group with fragile X syndrome (FXS), based on normal development scale. The sample has 10 boys, between 6 and 13 years and with FXS. All of them were submitted to language evaluation. The most part of them had the communication in linguistic form (80%), until 3 years old. It was considered that the data confirmed the significant delay in the acquisition and development of the communication, being necessary an early and specialized intervention.604981985Kaufmann, W.E., Reiss, A.L., Molecular and cellular genetics of fragile X syndrome (1999) Am J Med Genet, 88, pp. 11-24Turner, G., Webb, T., Wake, S., Robinson, H., Prevalence of fragile X syndrome (1996) Am J Med Genet, 64, pp. 196-197Keenan, E., Keane, V., Ramsey, L., Fragile X syndrome (1993) Irish Med J, 86, pp. 94-96Jacky, P.B., Ahuja, Y.R., Anyane-Yeboa, K., Guidelines for the preparation and analysis of the fragile X chromosome in lymphocytes (1991) Am J Med Genet, 38, pp. 400-403Vries, B.B.A., Halley, K.J.J., Oostra, B.A., Niermeuer, M.F., The fragile X syndrome (1998) J Med Genet, 35, pp. 579-589Jorde, L.B., Carey, J.C., Bamshad, M.J., White, R.L., (2000) Genética Médica, pp. 89-91. , Rio de Janeiro: Guanabara KooganHodapp, R.M., Dykens, E.M., Hagerman, R.J., Scheriner, R., Lachiewicz, A.M., Leckman, J.F., Developmental implications of changing trajectories of IQ in males with fragile X syndrome (1990) J Am Acad Child Adolesc Psychiatry, 29, pp. 214-219Reiss, A.L., Lee, J., Freund, L., Neuroanatomy of fragile X syndrome: The temporal lobe (1994) Neurology, 44, pp. 1317-1324Brown, T.W., Jenkins, E.C., Cohen, I.L., Fragile X and autism (1986) Am J Med Genet, 23, pp. 341-352Turner, G., Daniel, A., Frost, M., X-linked mental retardation, macroorchidism, and the Xq27 fragile site (1980) Pediatrics, 96, pp. 837-841Proops, R., Webb, T., The fragile X syndrome in the Martin-Bell-Renpenning syndrome and in males with other forms of familial mental retardation (1981) J Med Genet, 18, pp. 366-373Meryash, D.L., Szymanski, L.S., Gerald, P.S., Infantile autism associated with the fragile X syndrome (1982) J Aut Dev Disord, 12, pp. 295-301Levitas, A., Hagerman, R.J., Braden, M., Rimland, B., Mcbogg, P., Autism and the fragile X syndrome (1983) J Dev Behav Pediatr, 4, pp. 151-158Varley, C.K., Holm, V., Eren, M.O., Cognitive and psychiatric variability in three brothers with fragile X syndrome (1985) Devel Behav Pediatr, 6, pp. 87-90Guerreiro, M.M., (1993) Síndrome do X Frágil: Características Clínicas, Eletrencefalográficas e de Imagem, , Tese UNICAMP, CampinasGiacheti, C.M., (1992) Achados Fonoaudiológicos em Indivíduos com a Síndrome do Cromossomo X Frágil, , Tese, Escola Paulista de Medicina, São PauloFisch, G.S., Holden, J.J.A., Carpenter, N.J., Age related language characteristics of children and adolescents with fragile X syndrome (1999) Am J Med Genet, 83, pp. 253-256Hanson, D.M., Jackson, A.W., Hagerman, R.J., Speech disturbances (cluttering) in mildy impaired males with the Martin-Bell/fragile X syndrome (1986) Am J Med Genet, 23, pp. 195-206Paul, R., Dykens, E., Leckman, M.W., Breg, W.R., Cohen, D.J., A comparison of language characteristics of mentally retarded adults with fragile X syndrome and those with nonspecific mental retardation and autism (1987) J Aut Dev Disord, 17, pp. 457-468Sudhalter, V., Cohen, I.L., Silverman, W., Wolf Schein, E.G., Conversational analyses of males with fragile X, Down syndrome and autism: A comparison of the emergence of deviant language (1990) Am J Med Genet, 94, pp. 431-441Sudhalter, V., Hollis, S., Cohen, I.L., Syntatic delay and pragmatic deviance in the language of fragile X males (1991) Am J Med Genet, 38, pp. 493-497Howard-Peebles, P.M., Stoddard, G.R., Mims, M.G., Familial X-linked mental retardation, verbal disability and marker X chromosomes (1979) Am J Hum Genet, 31, pp. 214-222Spinelli, M., Rocha, A.C.O., Giachtil, C.M., Richieri-Costa, A., Word-finding difficulties, verbal paraphasias, and verbal dyspraxia in tem individual with fragile X syndrome (1995) Am J Med Genet, 60, pp. 39-43Cornish, K.M., Munir, F., Cross, G., Spatial cognition in males with fragile X syndrome: Evidence for a neuropsychological phenotype (1999) Cortex, 35, pp. 263-271Sukhalter, V., Maranion, M., Brooks, P., Expressive semantic deficit in the productive language of males with fragile X Syndrome (1992) Am J Med Genet, 43, pp. 65-71Brown, R.W., (1973) A First Language: The Early Stages, , Cambridge: Harvard Univ PressHopper, R., Naremore, R., (1978) Children's Speech 2.Ed., , New York: Harper & RowLaunay, C., (1989) Distúrbios da Linguagem, da Fala e da voz na Infância, pp. 17-31. , São Paulo: RocaCasby, M.W., Cumpata, J.F., A protocol for the assessment of prelinguistic intentional communication (1986) J Commun Disord, 19, pp. 251-260Braz, H.A., Pellicciotti, H.F., (1988) Exame de Linguagem TIPITI. 3.Ed., , São Paulo: Editora MNJ
