These chromosomes can frequently divide during mitosis or meiosis, although they usually degenerate. 22 Despite the clear characterisation of the molecular alteration and clinical presentations, we have not found any other described patient presenting [easap.asia]

• Short Stature

  Ring chromosome 13 (r(13)) is associated with several phenotypic features like intellectual disability, marked short stature, brain and heart defects, microcephaly and genital malformations in males, including undescended testes and hypospadias. [content.iospress.com]

  They showed a phenotype consistent with the “ring syndrome” with failure to thrive, minor dysmporphic features and no major anomalies. [tp.amegroups.com]

  Without treatment babies develop chest infections and often have very serious failure to thrive. Early institution of treatment greatly improves the health of babies with CF. [embryology.med.unsw.edu.au]

• Vomiting

  However, at 4 months Ethan became very ill with vomitting and diarrhea and would no longer eat anything by mouth. We did some testing, including a head MRI for his opthalmologist, and learned that he has polymicrogyria. [chromosome13deletion.com]

  The more severely affected patient showed a break point at band 13q32 in the long arm of the ring, whereas in the less severely affected the loss of material during ring formation was restricted to the telomere. [ncbi.nlm.nih.gov]
