Abstract

Transient neonatal zinc deficiency (TNZD) has a clinical presentation similar to that of acrodermatitis enteropathica but is caused by a low zinc concentration in maternal breast milk. TNZD becomes clinically evident during breastfeeding and is resolved by weaning and the introduction of complementary nutrition. We present a 4-month-old girl with TNZD due to a new autosomal dominant mutation (663delC) in the maternal SLC30A2 gene not previously described in the literature.

摘要

短暂性新生儿锌缺乏症(TNZD)的临床表现与肠病性肢端皮炎相似,但由母乳中锌浓度低引起。TNZD在母乳喂养期间临床上变得明显,并通过断奶和引入补充营养得以解决。我们报告一名4个月大的患有TNZD的女孩,其病因是母亲的SLC30A2基因出现一种新的常染色体显性突变(663delC),该突变在文献中未曾描述过。
