The c.1798A>G (p.T600A) alteration is located in exon 4 (coding exon 3) of the KBTBD2 gene. This alteration results from a A to G substitution at nucleotide position 1798, causing the threonine (T) at amino acid position 600 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
