Chromosome 6 Ring Syndrome

Ring Chromosome 6

CASE PRESENTATION: Here we present an accurate cyto-molecular characterization of a ring chromosome 6 in a 16-months-old Caucasian girl with mild motor developmental delay, cardiac defect, and facial anomalies. [ncbi.nlm.nih.gov]

Presentation of Case: Female, Caucasian, born in Southeast of Brazil, 6 years old. [sciencedomain.org]

  • Poor Growth

    Not that much known about it because rare but main feature is poor growth and development. At the beginning, well when diagnosed anyway, they said he may never walk talk etc. No-one knew what his potential was but he is doing really well. [netmums.com]

Management and Treatment Since seizures with RC20 syndrome are typically difficult to treat, seizure control is very important. Every case is different and complex. [epilepsy.com]
