MECP2 duplication syndrome in a patient from Cameroon

Area of Science:

• Genetics
• Neurodevelopmental Disorders

Background:

• MECP2 duplication syndrome (MDS) is an X-linked neurodevelopmental disorder.
• Caused by duplications in the Xq28 region, affecting the MECP2 gene.
• Core symptoms include hypotonia, intellectual disability, speech impairment, spasticity, seizures, and infections.

Observation:

• Phenotypic features of MDS in individuals of African descent are not well-documented.
• A male patient from Cameroon with MDS was identified.
• The patient had an inherited microduplication of Xq28 (610 kb) including MECP2, IRAK1, L1CAM, and SLC6A8 genes.

Findings:

• The patient presented with a phenotype consistent with MDS.
• This case highlights the genetic basis and clinical manifestations of MDS in an African individual.

Implications:

• This report contributes valuable data to the understanding of MDS.
• It specifically enhances knowledge regarding the presentation of MDS in individuals of African descent.
• Further research into ethnic variations of MDS is warranted.
