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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.3022G>A (p.A1008T) alteration is located in exon 7 (coding exon 7) of the BNC2 gene. This alteration results from a G to A substitution at nucleotide position 3022, causing the alanine (A) at amino acid position 1008 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
