Genes affected

NR5A2 (HGNC:7984): (nuclear receptor subfamily 5 group A member 2) The protein encoded by this gene is a DNA-binding zinc finger transcription factor and is a member of the fushi tarazu factor-1 subfamily of orphan nuclear receptors. The encoded protein is involved in the expression of genes for hepatitis B virus and cholesterol biosynthesis, and may be an important regulator of embryonic development.

Collection Method: clinical testing

The c.128C>T (p.P43L) alteration is located in exon 2 (coding exon 2) of the NR5A2 gene. This alteration results from a C to T substitution at nucleotide position 128, causing the proline (P) at amino acid position 43 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
