Antibiotic and anti-viral medications are used for infections until an investigational cultured thymus tissue transplant can be undergone. DiGeorge syndrome may be first spotted when an affected newborn has heart defects or convulsions from hypocalcemia due to malfunctioning parathyroid glands and low levels of parathyroid hormone (parathormone). [31][32] The number of genes affected by the deletion has been cited as approximately 30 to 50. These factors, along with the lower expense and easier testing mean that this MLPA probe could replace FISH in clinical testing. These include DGCR8 which is important for biogenesis of brain microDNA, SRPT5 which encodes a protein that interacts with the PARK2 protein, COMT which is involved in regulating dopamine levels, and microRNA miR-185 which is thought to target known PD loci LRRK2. In these cases the small amount of thymus tissue present provides adequate T-lymphocyte function. Individuals with fragile X syndrome nearly always have (in greater than 99% of cases) a full mutation of the FMR1 gene which means that they have over 200 CGG repeats and abnormal methylation of the gene.Methylation is a chemical change to the DNA that carries the genetic code .

The classical presentation is a triad of cardiac anomalies, hypoplastic thymus, and hypocalcaemia (resulting from parathyroid hypoplasia). These patients require prompt medical attention since they are severely immunocompromised. The outlook for people with DGS depends on the function of each affected organ system. Congenital health defects are problems with the structure of the heart. It is caused due to deletion of a section of chromosome 22 and hence is medically referred to as 22q11.2 deletion syndrome. [32], Research in mouse models has shown that deletion of Tbx1 leads to several defects similar to those seen in humans, mainly affecting development of the great arteries and the thymus.[38][39].
