• Consequence: JAZF1 NM_175061.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.643

Genes affected

JAZF1 (HGNC:28917): (JAZF zinc finger 1) This gene encodes a nuclear protein with three C2H2-type zinc fingers, and functions as a transcriptional repressor. Chromosomal aberrations involving this gene are associated with endometrial stromal tumors. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.189 is higher than 0.05.
