The c.392A>T (p.H131L) alteration is located in exon 4 (coding exon 1) of the KIAA1551 gene. This alteration results from a A to T substitution at nucleotide position 392, causing the histidine (H) at amino acid position 131 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
