Developmental and epileptic encephalopathy, 68

Pathogenic:1Uncertain:1

Uncertain significance, criteria provided, single submitter	curation	SIB Swiss Institute of Bioinformatics	Mar 12, 2019	This variant is interpreted as a variant of uncertain significance for Epileptic encephalopathy, early infantile, 68, autosomal recessive. The following ACMG Tag(s) were applied: PM2 : Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 : Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1 : Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease. PP1 upgraded in strength to Moderate (PMID:29846532). -
