Collection Method:clinical testing

The c.1939G>A (p.G647S) alteration is located in exon 9 (coding exon 9) of the KLHL1 gene. This alteration results from a G to A substitution at nucleotide position 1939, causing the glycine (G) at amino acid position 647 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
