Genes affected

NACC2 (HGNC:23846): (NACC family member 2) Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; histone deacetylase binding activity; and protein homodimerization activity. Involved in several processes, including negative regulation of G1/S transition of mitotic cell cycle by negative regulation of transcription from RNA polymerase II promoter; positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage; and protein homooligomerization. Located in chromatin; mitochondrion; and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

The c.1585G>A (p.G529S) alteration is located in exon 6 (coding exon 5) of the NACC2 gene. This alteration results from a G to A substitution at nucleotide position 1585, causing the glycine (G) at amino acid position 529 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
