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]

YWHAG Gene-Disease associations (from GenCC):

• developmental and epileptic encephalopathy, 56

  Inheritance: AD Classification: DEFINITIVE, STRONG Submitted by: Ambry Genetics, Illumina, Labcorp Genetics (formerly Invitae)
• undetermined early-onset epileptic encephalopathy

  Inheritance: AD Classification: STRONG, SUPPORTIVE Submitted by: Orphanet, G2P

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 10 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 2.9513 (below the threshold of 3.09). Trascript score misZ: 3.8136 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy, 56, undetermined early-onset epileptic encephalopathy.
• BP4: Computational evidence support a benign effect (MetaRNN=0.3972447).
