Genes affected

YWHAG (HGNC:12852): (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein gamma) This gene product belongs to the 14-3-3 family of proteins which mediate signal transduction by binding to phosphoserine-containing proteins. This highly conserved protein family is found in both plants and mammals, and this protein is 100% identical to the rat ortholog. It is induced by growth factors in human vascular smooth muscle cells, and is also highly expressed in skeletal and heart muscles, suggesting an important role for this protein in muscle tissue. It has been shown to interact with RAF1 and protein kinase C, proteins involved in various signal transduction pathways. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.814

This variant is interpreted as a Uncertain Significance, for Epileptic encephalopathy, early infantile, 56, Autosomal Dominant inheritance. 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. PM6 => Assumed de novo, but without confirmation of paternity and maternity (PMID:28777935). PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. -
