The c.1174A>G (p.T392A) alteration is located in exon 10 (coding exon 10) of the KIAA1524 gene. This alteration results from a A to G substitution at nucleotide position 1174, causing the threonine (T) at amino acid position 392 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
