Evidence/Notes:

NEFL was first gene reported in relation to autosomal dominant Charcot-Marie-Tooth disease in 2000 (Mersiyanova et al., PMID: 10841809). Based on the literature we differentiate between autosomal dominant NEFL CMT (MONDO:0015626), autosomal recessive NEFL CMT (MONDO:0018993). The split curation for autosomal dominant and recessive CMT has been curated separately. Three different variants (stop-gained) that have been reported in 3 probands in 3 publications (PMIDs: 20039262, 29191368, 19158810) are included in this curation. The mechanism of pathogenicity appears to be a loss-of-function due to the lack of NF network development as described in the in-vitro studies. Functional experimental evidence supports NEFL in controls, patients, and animal models (PMIDs: 17881652, 9388258, 28654681, 26383514, 35237613, 9398473, 8468353). In-vitro functional studies for all described variants depict failure of development in NF networks and lack of NF distribution. In summary, NEFL is definitively associated with autosomal recessive axonal Charcot-Marie-Tooth disease. This has been repeatedly demonstrated in both the research and clinical diagnostic settings and has been upheld over time.
