Sažetak
Partial trisomy on chromosome 7 (7q) is a rare condition resulting from duplication of the 7q long arm. It is usually associated with
delayed psychomotor development, characteristic phenotypic features and profound learning disabilities. The clinical picture is
highly variable and depends on the size of duplicated segments. The aim of this study was to examine the range of receptive
vocabulary and understanding of grammar, acquisition of early reading and writing skills, speech and motor skills, voice quality and
narrative abilities in a boy with partial trisomy 7q. The child’s chronological age during the study period was 7 years and 10 months.
Data analysis showed that the boy had a reduced range of receptive vocabulary and achieved low scores on the test of grammar
reception (TROG-2: HR). His speech and motor skills were impaired, as well as his voice quality. The boy had acquired some early
reading and writing skills. He showed good results in the variables of breaking down sentences to words, variable of phonemic
awareness and phonological naming of uppercase and lowercase letters.
