Early clamping is categorized as within the first 60 seconds after birth, whereas late umbilical cord clamping is classified as more than one minute after the birth. There is no evidence indicating that time to umbilical cord clamping has had an effect on umbilical granuloma formation or on additional neonatal morbidity outcomes. Complications
If an infection occurs, omphalitis may occur. Recurrence risk
The various treatment modalities of umbilical granuloma result in various recurrence risks. In a systematic review, following infants through weeks 1, 3 and 6 post-treatment for umbilical granuloma, newborns treated with silver nitrate presented with a 9% recurrence risk, whereas newborns treated with common salt presented null recurrence.

This report further expands the phenotypic spectrum to include the possibility of normal intelligence as corroborated by formal, longitudinal psycho-educational testing.The presence of two homologous low copy repeats either side of the deletion break-point suggests that non-allelic homologous recombination is the likely mechanism underlying this syndrome. Genetics
The microdeletion, around 1.6 million base pairs, in length and encompasses 5 known genes and 17 uncharacterised transcripts. These include transferrin receptor, choline-phosphate cytidylyltransferase A, RNF168, serine/threonine-protein kinase, nuclear cap-binding protein complex, melanotransferrin, DLG1 and D-beta-hydroxybutyrate dehydrogenase

Research
Research on the risk for developing schizophrenia in Ashkenazi Jews and other populations showed that 3q29 microdeletion syndrome leads to a significant higher rate of schizophrenia. In addition, a deletion at 3q29 was found to confer an increase to the odds of developing schizophrenia in a study of copy number variants and their effect on that disorder. References
