Genes affected

BNC1 (HGNC:1081): (basonuclin zinc finger protein 1) This gene encodes a zinc finger protein present in the basal cell layer of the epidermis and in hair follicles. It is also found in abundance in the germ cells of testis and ovary. This protein is thought to play a regulatory role in keratinocyte proliferation and it may also be a regulator for rRNA transcription. Disruption of this gene has been implicated in premature ovarian failure as well as testicular premature aging. [provided by RefSeq, Sep 2020]

The c.2672A>G (p.D891G) alteration is located in exon 5 (coding exon 5) of the BNC1 gene. This alteration results from a A to G substitution at nucleotide position 2672, causing the aspartic acid (D) at amino acid position 891 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
