A case report of de novo missense FOXP1 mutation in a non-Caucasian patient with global developmental delay and severe speech impairment
نویسندگان
چکیده
The FOXP protein family (FOXP1-4) is a group of transcription factors that play important roles in embryological, immunological, hematological, and speech and language development. Here, we report FOXP1 de novo mutation and severe speech delay in an individual belonging to a non-Caucasian population.

Syndromic Intellectual Disability Caused by a Novel Truncating Variant in AHDC1: A Case Report
Mutations in the AHDC1 gene are associated with the Xia-Gibbs syndrome (XGS), a sporadic genetic disorder characterised by developmental delay, intellectual disability, hypotonia, obstructive sleep apnoea, dysmorphic facial features, and cerebral malformations with plagiocephaly. Here we report the case of a 13-year-old Colombian female patient with a history of developmental delay, speech dela...
متن کاملIdentification and functional characterization of de novo FOXP1 variants provides novel insights into the etiology of neurodevelopmental disorder.
De novo disruptions of the neural transcription factor FOXP1 are a recently discovered, rare cause of sporadic intellectual disability (ID). We report three new cases of FOXP1-related disorder identified through clinical whole-exome sequencing. Detailed phenotypic assessment confirmed that global developmental delay, autistic features, speech/language deficits, hypotonia and mild dysmorphic fea...

Rett syndrome (RS) is a neurodevelopmental infantile disease characterized by an early normal psychomotor development followed by a regression in the acquisition of normal developmental stages. In the majority of cases, it leads to a sporadic mutation in the MECP2 gene, which is located on the X chromosome. However, this syndrome has also been associated with microdeletions, gene translocations...

Background The X-linked cyclin-dependent kinase like 5 (CDKL5/STK9) gene has been shown to be responsible for a severe encephalopathy condition characterized by early onset of epilepsy and severe developmental delay. CDKL5 mutations have been shown to be more frequent among female patients. Results Here we report a 6- month male patient, second child of a healthy non consanguineous in the Irani...
متن کاملA de novo missense mutation in ZMYND11 is associated with global developmental delay, seizures, and hypotonia
Recently, mutations in the zinc finger MYND-type containing 11 (ZMYND11) gene were identified in patients with autism spectrum disorders, intellectual disability, aggression, and complex neuropsychiatric features, supporting that this gene is implicated in 10p15.3 microdeletion syndrome. We report a novel de novo variant in the ZMYND11 gene (p.Ser421Asn) in a patient with a complex neurodevelop...
