In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 31)
• Consequence: MAU2 NM_015329.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -3.57

Genes affected

MAU2 (HGNC:29140): (MAU2 sister chromatid cohesion factor) Enables protein N-terminus binding activity. Involved in cohesin loading and maintenance of mitotic sister chromatid cohesion. Located in chromatin and nuclear body. Part of Scc2-Scc4 cohesin loading complex. [provided by Alliance of Genome Resources, Apr 2022]
