Also, people with the genetic disease DiGeorge syndrome, often born with parathyroid glands that are too small and can't produce enough parathyroid hormone.

或是由于患有DiGeorge综合症，生来甲状旁腺就太小，不能产生足够的甲状旁腺激素。

Dr Bearden had a similar approach with DiGeorge syndrome and its opposite.

Bearden 博士对 DiGeorge 综合症及其对立面采取了类似的方法。

This can be caused surgical removal or autoimmune destruction of the parathyroid gland, as well as congenital problems involving the parathyroid gland like DiGeorge syndrome, or deficiency in magnesium which is needed for parathyroid hormone production.

原因可能是手术切除了甲状旁腺，或者自身免疫性疾病对甲状旁腺的攻击，也可能是因为像DiGeorge综合征这种累及甲状旁腺的先天性疾病，或者缺少合成甲状旁腺激素必要的元素：镁。

Dr Bearden works on DiGeorge syndrome, likewise eponymously identified in 1968, and caused by a deletion of part of chromosome 22. Both have counterparts, noted more recently, that result from an extra copy of the labile chromosomal section.

Bearden 博士致力于研究 DiGeorge 综合症，该综合症同样于 1968 年以同名身份确定， 由 22 号染色体的一部分缺失引起。最近注意到， 两者都有对应物， 是由不稳定染色体部分的额外副本引起的。
