| Ataxia and cerebellar anomalies - narrow panel v8.57 | JKAMP | Ida Ertmanska Added comment: Comment on list classification: There are 14 affected individuals from 10 unrelated families reported in literature with biallelic JKAMP variants and a neurodevelopmental disorder. MRI findings were abnormal in 12/14 subjects, including cortical and or cerebral atrophy (11/14) and delayed myelination (6/14). Based on available evidence, JKAMP should be promoted to Green for Ataxia and cerebellar anomalies - narrow panel. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Ida Ertmanska gene: JKAMP was added gene: JKAMP was added to Ataxia and cerebellar anomalies - narrow panel. Sources: Literature Mode of inheritance for gene: JKAMP was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: JKAMP were set to 41643666 Phenotypes for gene: JKAMP were set to neurodevelopmental disorder, MONDO:0700092 Review for gene: JKAMP was set to GREEN Added comment: PMID: 41643666 Chacon-Millan et al., 2026 Report of 14 affected individuals from 10 unrelated families with biallelic JKAMP variants and a neurodevelopmental disorder. Individuals came from European and Arab backgrounds; age range 18mo - 25yrs. Several frameshift, missense and splice variants reported (homozygous and compound heterozygous states). Phenotype spectrum: moderate-profound neurodevelopmental delay and ID (14/14), neurodevelopmental regression (5/14), early onset epilepsy (14/14, median age of onset 6.5 months), hypotonia (13/14), microcephaly (5/14, severity not stated), various ocular manifestations (5/14), genitourinary malformations (3/14), and other (less common). MRI findings: cortical and or cerebral atrophy (11/14), delayed myelination (6/14). Additional functional evidence: Knockout jkamp-/- zebrafish were generated using CRISPR. Roughly half of the knockout fish had a mild phenotype, and half a 'severe' phenotype - similar to variable severity seen in patient cohort. Morphant phenotype consisted of smaller eyes and heads, and reduced expression of a myelin marker mbpa, partially recapitulating the human phenotype. JKAMP is not yet linked to a disease entity in OMIM, Gene2Phenotype, or ClinGen (resources accessed 10th Feb 2026). Sources: Literature |
