What this study looked at
The neuronal ceroid lipofuscinoses (NCL) are a group of rare inherited disorders — the Batten diseases — that cause progressive neurological decline in children. This study reviewed the records of 27 patients with NCL, 15 of whom had atypical clinical or pathological features, in order to characterise how these rarer variants present.
Key takeaways
- The atypical forms tended to cluster in the late-infantile and juvenile age groups.
- Many of the atypical late-infantile cases were suggestive of CLN6, while atypical juvenile cases tended to follow a more protracted course.
- Advances in biochemistry and genetics are beginning to separate some of these variants into distinct diseases, yet careful clinical and pathological assessment remained the most useful way to identify atypical NCL.
Why it matters
Recognising these unusual presentations helps clinicians avoid missing NCL when a child does not fit the textbook picture.
