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]

The c.493C>T (p.L165F) alteration is located in exon 1 (coding exon 1) of the EPM2AIP1 gene. This alteration results from a C to T substitution at nucleotide position 493, causing the leucine (L) at amino acid position 165 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
