The c.1897G>T (p.A633S) alteration is located in exon 15 (coding exon 15) of the IMMT gene. This alteration results from a G to T substitution at nucleotide position 1897, causing the alanine (A) at amino acid position 633 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
