Neonatal tricho-hepato-enteric syndrome caused by SKIV2L gene mutation: a case report / 中华围产医学杂志

ABSTRACT

We here report the diagnosis and treatment of tricho-hepato-enteric syndrome in a female neonate. The 11-day-old patient, born at a gestational age of 38 weeks and with a birth weight of 1 700 g, was admitted to the Affiliated Hospital of Jining Medical University in January 2019 due to "skin stained yellow for 6 d". She presented with yellow, thin, and sparse hair that was easy to fall off, intractable diarrhea, repeated fever, and slow weight gain, further complicated by congenital heart disease. After 25-days of treatment, the child's infection was under control, but still had diarrhea. The baby girl was discharge later on request of her parents, but readmitted at the age of 3 months due to pulmonary infection. Delayed development, malnutrition, prominent forehead, wide eye distance, low nasal bridge, hepatomegaly, and intractable diarrhea were also observed. Whole exome sequencing identified a homozygous mutation of c.2344delC(p.His782fs) in SKIV2L gene in the baby, and both her parents were heterozygous carriers of the mutation at this site. She was diagnosed with SKIV2L gene mutation-induced tricho-hepato-enteric syndrome. The patient suffered from sustained diarrhea and recurrent infection and died of infection at 4 months of age after her parents' decision to withdraw treatment.
