Genes affected

OSGIN2 (HGNC:1355): (oxidative stress induced growth inhibitor family member 2) Predicted to enable growth factor activity. Predicted to be involved in negative regulation of cell growth. [provided by Alliance of Genome Resources, Apr 2022]

NBN (HGNC:7652): (nibrin) Mutations in this gene are associated with Nijmegen breakage syndrome, an autosomal recessive chromosomal instability syndrome characterized by microcephaly, growth retardation, immunodeficiency, and cancer predisposition. The encoded protein is a member of the MRE11/RAD50 double-strand break repair complex which consists of 5 proteins. This gene product is thought to be involved in DNA double-strand break repair and DNA damage-induced checkpoint activation. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.008452892).
• BP6: Variant 8-89924970-G-C is Benign according to our data. Variant chr8-89924970-G-C is described in ClinVar as [Benign]. Clinvar id is 713505.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0119 (1810/152322) while in subpopulation AFR AF= 0.0415 (1725/41568). AF 95% confidence interval is 0.0399. There are 36 homozygotes in gnomad4. There are 877 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 36 AR gene
