Ataxia and cerebellar anomalies - narrow panel v8.17 EEFSEC Arina Puzriakova Phenotypes for gene: EEFSEC were changed from neurodevelopmental disorder, MONDO:0700092; hereditary cerebellar ataxia, MONDO:0100310 to Neurodevelopmental disorder with progressive spasticity and brain abnormalities, OMIM:621102
Ataxia and cerebellar anomalies - narrow panel v7.15 EEFSEC Achchuthan Shanmugasundram changed review comment from: PMID:39753114 reported nine different individuals from eight unrelated families with a selenopathy with early-onset neurodegeneration. Thy were all identified with six different biallelic variants in EEFSEC gene, of which seven families had variants in homozygous state, while one family had variants in compound heterozygous state. They presented with global developmental delay, moderate or severe cognitive impairment, progressive spasticity, ataxia, and seizures. In addition, cerebral MRI primarily demonstrated a cerebellar pathology, including hypoplasia and progressive atrophy. Ataxia was reported in four unrelated cases, cerebellar hypoplasia in one and cerebellar atrophy in four cases from three families.

This gene has not yet been associated with any relevant phenotypes either in OMIM or in Gene2Phenotype.

In line with the clinical phenotype, an eEFSec-RNAi Drosophila model displays progressive impairment of motor function, which is reflected in the synaptic defects in this model organisms.
