Genes affected

BNC2 (HGNC:30988): (basonuclin zinc finger protein 2) This gene encodes a conserved zinc finger protein. The encoded protein functions in skin color saturation. Mutations in this gene are associated with facial pigmented spots. This gene is also associated with susceptibility to adolescent idiopathic scoliosis. [provided by RefSeq, Jul 2016]

BNC2 Gene-Disease associations (from GenCC):

• lower urinary tract obstruction, congenital

  Inheritance: AD Classification: DEFINITIVE, STRONG, MODERATE Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• posterior urethral valve

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.279 is higher than 0.05.
