Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_175061.4(JAZF1):​c.188+27507G>A variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.944 in 152,196 control chromosomes in the GnomAD database, including 67,923 homozygotes. 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: 𝑓 0.94 (67923 hom., cov: 30)
• Consequence: JAZF1 NM_175061.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.463

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=-0.96).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.977 is higher than 0.05.
