The c.701A>G (p.E234G) alteration is located in exon 3 (coding exon 3) of the KBTBD4 gene. This alteration results from a A to G substitution at nucleotide position 701, causing the glutamic acid (E) at amino acid position 234 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
