The c.3269G>A (p.R1090K) alteration is located in exon 11 (coding exon 10) of the BTBD7 gene. This alteration results from a G to A substitution at nucleotide position 3269, causing the arginine (R) at amino acid position 1090 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
