Genes affected

ZYG11B (HGNC:25820): (zyg-11 family member B, cell cycle regulator) Involved in positive regulation of proteasomal ubiquitin-dependent protein catabolic process and protein quality control for misfolded or incompletely synthesized proteins. Part of Cul2-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ZYG11B. . Gene score misZ 3.9832 (greater than the threshold 3.09). Trascript score misZ 4.3282 (greater than threshold 3.09). GenCC has associacion of gene with multiple congenital anomalies/dysmorphic syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.899

The c.1823A>G (p.H608R) alteration is located in exon 11 (coding exon 11) of the ZYG11B gene. This alteration results from a A to G substitution at nucleotide position 1823, causing the histidine (H) at amino acid position 608 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
