Genes affected

BTG4 (HGNC:13862): (BTG anti-proliferation factor 4) The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein can induce G1 arrest in the cell cycle. [provided by RefSeq, Jul 2008]

• female infertility

  Inheritance: AR Classification: MODERATE Submitted by: Franklin by Genoox

ACMG classification

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.312 CDS is truncated, and there are 1 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-111497242-GGAAT-G is Pathogenic according to our data. Variant chr11-111497242-GGAAT-G is described in ClinVar as [Pathogenic]. Clinvar id is 977517.Status of the report is no_assertion_criteria_provided, 0 stars.
