The c.1891G>A (p.A631T) 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 1891, causing the alanine (A) at amino acid position 631 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
