PURA-related severe neonatal hypotonia-seizures-encephalopathy syndrome Pathogenic:1
For these reasons, this variant has been classified as Pathogenic. Disruption of the initiator codon has been observed in individual(s) with clinical features of PURA syndrome (PMID: 27148565, 32337850). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the PURA mRNA. The next in-frame methionine is located at codon 104. -
