The c.2551T>A (p.S851T) alteration is located in exon 21 (coding exon 21) of the KIAA1524 gene. This alteration results from a T to A substitution at nucleotide position 2551, causing the serine (S) at amino acid position 851 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
