The c.4172G>T (p.G1391V) alteration is located in exon 17 (coding exon 17) of the KIAA1429 gene. This alteration results from a G to T substitution at nucleotide position 4172, causing the glycine (G) at amino acid position 1391 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
