Juvenile Huntington Disease

Huntington disease (HD) is caused by a pathologic cytosine-adenine-guanine (CAG) trinucleotide repeat expansion in the HTT gene. Typical adult-onset disease occurs with a minimum of 40 repeats. With more than 60 CAG repeats, patients can have juvenile-onset disease (jHD), with symptom onset by the age of 20 years. We report a case of a boy with extreme early onset, paternally inherited jHD, with symptom onset between 18 and 24 months. He was found to have 250 to 350 CAG repeats, one of the largest repeat expansions published to date. At initial presentation, he had an ataxic gait, truncal titubation, and speech delay. Magnetic resonance imaging showed cerebellar atrophy. Over time, he continued to regress and became nonverbal, wheelchair-bound, gastrostomy-tube dependent, and increasingly rigid. His young age at presentation and the ethical concerns regarding HD testing in minors delayed his diagnosis.

Background: We aim to describe the long term follow-up of a cohort of children exposed in utero to the Zika virus. Methods: Descriptive study of a cohort of microcephalic children due to Zika virus. Logistic regression was used to evaluate variables associated with worse prognosis epilepsy. Results: We followed 28 children (15 females), with a median follow-up of 24 months (IQR = 12-28). During the follow-up, 1 infant died. The median head circumference at birth was 29 cm (IQR = 27-31). All presented a global developmental delay. The most frequent central nervous system abnormalities were on cortical development in 22 participants; dysgenesis of corpus callosum in 13; ventriculomegaly in 25; and calcifications in 24. A total of 9 presented ocular abnormalities, 4 auditory impairment. During follow-up, 12 presented with sleep disorders, 10 with irritability, and 23 with epilepsy (2 with generalized tonic-clonic, 3 with generalized tonic-clonic and spasms, 12 with spasms, 3 tonic and spasms, and 3 motor focal and spasms). The median age at the begin of the epilepsy was 4 months (IQR = 2-10), the median number of drugs used to control the epilepsy was 2 (IQR = 2-3). Maternal illicit drug use during pregnancy was associated with worse prognosis epilepsy (Lennox-Gastaut syndrome, West syndrome, or status epilepticus). A total of 19 presented with dysphagia, 10 children required gastrostomy. Conclusion: Children with microcephaly due to Zika virus presented with several complications during follow-up, as epilepsy, spastic diplegia, and global developmental delay.
