Genes affected

YWHAZ (HGNC:12855): (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta) 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 99% identical to the mouse, rat and sheep orthologs. The encoded protein interacts with IRS1 protein, suggesting a role in regulating insulin sensitivity. Several transcript variants that differ in the 5' UTR but that encode the same protein have been identified for this gene. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a chain 14-3-3 protein zeta/delta (size 244) in uniprot entity 1433Z_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_145690.3
• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_145690.3.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
