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 Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a modified_residue Phosphotyrosine (size 0) in uniprot entity 1433G_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.977
• PP5: Variant 7-76329923-T-G is Pathogenic according to our data. Variant chr7-76329923-T-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 549482.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=1, Uncertain_significance=1}.

This variant is interpreted as a Likely Pathogenic, for Neurodevelopmental disorder. The following ACMG Tag(s) were applied: PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM6 => Assumed de novo, but without confirmation of paternity and maternity (PMID:28777935). PM1 => Located in a mutational hot spot and/or critical and well-established functional domain (e.g., active site of an enzyme) without benign variation (http://www.uniprot.org/uniprot/P61981#showFeaturesTable) (PMID:28777935). PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. -
