The c.1324G>T (p.D442Y) alteration is located in exon 12 (coding exon 10) of the IVNS1ABP gene. This alteration results from a G to T substitution at nucleotide position 1324, causing the aspartic acid (D) at amino acid position 442 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
