Symptoms of what was formerly known as DiGeorge syndrome were variable and the underlying cause (deletions of 22q11.2) is also responsible for related/overlapping syndromes. Terms such as 'complete' and 'partial' DiGeorge syndrome have been used in reference to individual cases which had all the characteristic signs and symptoms (e.g., hypoparathyroidism, absent thymus, and  heart disease) verses those with only some of them.<ref>Hernández-Nieto L, Yamazaki-Nakashimada MA, Lieberman-Hernández E, Espinosa-Padilla SE.

Overview

Based on the subtype, DGS may be classified as either partial or complete.

Classification

There is no established system for the classification of DGS.

However, based on the severity, it may be classified as partial DGS and complete DGS.

Since symptoms of DiGeorge syndrome were variable and the underlying cause (deletions of 22q11.2) is responsible for other related/overlapping syndromes, using terms such as 'complete' and 'partial' DiGeorge syndrome is in reference to individual cases which had all the characteristic signs and symptoms (e.g., hypoparathyroidism, absent thymus, and  heart disease) versus those with only some of them.[1]
