About this study

Official title: Better Understanding Slow Language Impairment: Cognitive and Genetic Mechanisms

This study was designed to examine the development of children aged 6 to 10 with slow language impairment (SLI). The aim was threefold: (1) to investigate language skills of children with SLI at different levels - formal, semantic, pragmatic- in comparison with those of control children; (2) to test a procedural deficit hypothesis: abnormal development in the procedural memory system could account for some language deficits; (3) to make genotype-phenotype comparisons, focusing on the different levels of language development and on procedural skills. The main hypothesis is that genetic mutations, contingently epistatique, will lead to procedural learning deficit, which will have a negative impact on language skills at the formal level and consequently on semantic and pragmatic levels.

Read the detailed description

To test the main hypothesis, 60 SLI children and 100 controls children will be included on the protocol. Due to the lack of specific standardized tests, the diagnostic of specific language-impaired French children is a challenge. Thus, both a battery of standardized and non-standardized language tests (assessing the different levels: formal, semantic and pragmatic) will be administered to children to establish a profile of weaknesses for each child with SLI and to examine the relationships between SLI and procedural learning. DNA sampling will be conducted on each child, SLI and control, to allow subsequently the molecular analyses in order to run the association comparisons between behavioral data and genetic profiles.

The protocol includes as verbal standardized tests: the Echelle "Vocabulaire en Images Peabody" (EVIP;), the "Epreuve de COmpre´hension Syntaxico-SEmantique" (ECOSSE), two specific subtests (lexicon and grammar) of the "Evaluation du Langage Oral" (ELO;), and as non-standardized tests: a semantic inference task (drawing the meaning of new words from the context, and the meaning of predicative metaphors), and a pragmatic inference task (understanding of indirect requests, on speakers' intention meaning and on irony). The procedural learning skills will be assessed thanks to a serial reaction task, specifically adapted for children).

The complete sequencing of FoXP2 gene, as well as the genotyping of the 44 single nucleotide polymorphisms (SNPs), located in the risk haplotypes identified in ATP2C2, CMIP, CNTNAP2 genes and in the KIAA0319/TTRAP/THEM2 locus, will be conducted.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Language development

    Assessment using :

    • For each of the following tasks, the number of correct answers of children at the questions is collected. These scores can be aggregated (addition).Echelle "Vocabulaire en Images Peabody" (EVIP; Dunn, The´riault-Whalen, \& Dunn, 1993). Scale range: 0-170.
    • the "Epreuve de COmpréhension Syntaxico-SEmantique" (ECOSSE; Lecocq, 1996) task. Scale range: 0-92. ,
    • two specific subtests (lexicon and grammar) of the "Evaluation du Langage Oral" (ELO; Khomsi, 2001). Scale range: 0-57, respectively 32 (Lexicon subtest) and 25 'grammar subtest)
    • non-standardized tests: a semantic inference task (drawing the meaning of new words from the context, and the meaning of predicative metaphors), and a pragmatic inference task (understanding of indirect requests, on speakers' intention meaning and on irony). Scale range: 0-55.

    Measured: Day 0

  2. Procedural learning

    Assessment thanks to an experimental serial reaction task, specifically adapted for children (Gabriel et al., 2011). This is a computerized task in which are collected reaction times of children according to the spatial input occurrences on the screen, which follow a fixed procedure that is to be implicit learned (procedural learning).

    Measured: Day 0

Secondary outcomes (1)
  1. DNA sampling

    The complete sequencing of FoXP2 gene, as well as the genotyping of the 44 single nucleotide polymorphisms (SNPs), located in the risk haplotypes identified in ATP2C2 (Newbury et al., 2009), CMIP (Newbury et al., 2009), CNTNAP2 (Vernes et al. 2008) genes and in the KIAA0319/TTRAP/THEM2 locus (Pinel et al., 2012), will be conducted.

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

A study of Slow Language Impairment, run by CHU de Reims at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 9 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Christine RAYNAUD (0326784649 ext. +33, craynaud@chu-reims.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Language development (time frame: Day 0). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jun 2020.
