Mendeliome v1.2398 CRMP1 Zornitza Stark Marked gene: CRMP1 as ready
Mendeliome v1.2398 CRMP1 Zornitza Stark Gene: crmp1 has been classified as Green List (High Evidence).
Mendeliome v1.2398 CRMP1 Zornitza Stark Phenotypes for gene: CRMP1 were changed from neurodevelopmental disorder, MONDO:0700092 to neurodevelopmental disorder, MONDO:0700092, CRMP2-related
Mendeliome v1.2397 CRMP1 Zornitza Stark Classified gene: CRMP1 as Green List (high evidence)
Mendeliome v1.2397 CRMP1 Zornitza Stark Gene: crmp1 has been classified as Green List (High Evidence).
Mendeliome v1.2396 CRMP1 Zornitza Stark reviewed gene: CRMP1: Rating: GREEN; Mode of pathogenicity: None; Publications: ; Phenotypes: neurodevelopmental disorder, MONDO:0700092, CRMP2-related; Mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Mendeliome v1.2386 CRMP1 Achchuthan Shanmugasundram changed review comment from: PMID:36511780 reported the identification of three different heterozygous de novo variants in the CRMP1 gene (p.(Pro589Leu), p.(Thr427Met) & p.(Phe351Ser)) in three unrelated individuals with a neurodevelopmental disorder presenting with muscular hypotonia, intellectual disability, and/or autism spectrum disorder. ID was moderate in two of them, while IQ was normal in one. There is also functional evidence available for these variants.

PMID:39758889 reported the identification of a novel heterozygous de novo frameshift variant in CRMP1 (p.(Lys586fs)) in a 9-year-old male patient presenting with phenotypes such as autism, language delay, hyperactivity, and learning disabilities. This patient was reported with moderate ID.

There are three unrelated cases reported with moderate intellectual disability and with monoallelic CRMP1 variants. However, one patient with a different monoallelic CRMP1 variant had normal IQ. Hence, this gene should be rated amber with current evidence.
