Hereditary neuropathy v1.380 MAP1B Arina Puzriakova Classified gene: MAP1B as Red List (low evidence)
Hereditary neuropathy v1.380 MAP1B Arina Puzriakova Added comment: Comment on list classification: Rating Red as only a single family reported with a homozygous MAP1B variant and polyneuropathy. Furthermore, the article identified by the expert reviewer is currently not published in PubMed. Additional cases required to support this gene-disease association.

Hereditary neuropathy v1.368 MAP1B Aleš Maver gene: MAP1B was added
gene: MAP1B was added to Hereditary neuropathy. Sources: Other
Mode of inheritance for gene: MAP1B was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: MAP1B were set to https://n.neurology.org/content/92/15_Supplement/P3.4-037
Phenotypes for gene: MAP1B were set to Giant Axonal Neuropathy-like phenotype, polyneuropathy

Added comment: A single consanguineous family with three sibs affected by giant axonal neuropathy has been reported with walking difficulty, progressive lower extremity weakness and ataxia. All affected sibs were homozygous for the c.5521A>G, p.M1841V variant in MAP1B. Two brothers homozygous for the variant were also reported to have body mass index over 40. Nerve conduction studies revealed a severe sensory motor polyneuropathy.
