Genes affected
EPM2AIP1 (HGNC:19735): (EPM2A interacting protein 1) The EPM2A gene, which encodes laforin, is mutated in an autosomal recessive form of adolescent progressive myoclonus epilepsy. The protein encoded by this gene binds to laforin, but its function is not known. This gene is intronless. [provided by RefSeq, Oct 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.902T>C (p.I301T) alteration is located in exon 1 (coding exon 1) of the EPM2AIP1 gene. This alteration results from a T to C substitution at nucleotide position 902, causing the isoleucine (I) at amino acid position 301 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
