The c.875A>G (p.Q292R) alteration is located in exon 4 (coding exon 4) of the KBTBD4 gene. This alteration results from a A to G substitution at nucleotide position 875, causing the glutamine (Q) at amino acid position 292 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
