Tricho-hepato-enteric syndrome (THES), a rare autosomal recessive disorder caused by variants in the SKIC3 or SKIC2 gene, is characterized by intractable diarrhea, woolly hair, growth restriction and liver disease. Here we report a neonatal case of THES with neonatal hemochromatosis, in which the novel compound heterozygous SKIC3 variants NM_014639.4:c.815_816del p.(Gly272AlafsTer9) and NM_014639.4:c.2284G>A p.(Gly762Arg) were identified. Further research is needed to elucidate the mechanisms underlying iron metabolism dysregulation in THES.
毛发-肝脏-肠道综合征（THES）是一种由SKIC3或SKIC2基因变异引起的罕见常染色体隐性疾病，其特征为顽固性腹泻、羊毛状毛发、生长受限和肝脏疾病。在此，我们报告一例患有新生儿血色素沉着症的THES新生儿病例，其中鉴定出了新的复合杂合SKIC3变异NM_014639.4:c.815_816del p.(Gly272AlafsTer9)和NM_014639.4:c.2284G>A p.(Gly762Arg)。需要进一步研究以阐明THES中铁代谢失调的潜在机制。
