The c.2849G>T (p.W950L) alteration is located in exon 20 (coding exon 20) of the KIAA1324L gene. This alteration results from a G to T substitution at nucleotide position 2849, causing the tryptophan (W) at amino acid position 950 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
