Genes affected

NKX3-2 (HGNC:951): (NK3 homeobox 2) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in cell differentiation; negative regulation of chondrocyte differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; embryonic skeletal system development; and intestinal epithelial cell development. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.898C>G (p.R300G) alteration is located in exon 2 (coding exon 2) of the NKX3-2 gene. This alteration results from a C to G substitution at nucleotide position 898, causing the arginine (R) at amino acid position 300 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
