Collection Method: clinical testing

The c.460A>T (p.T154S) alteration is located in exon 5 (coding exon 5) of the IDNK gene. This alteration results from a A to T substitution at nucleotide position 460, causing the threonine (T) at amino acid position 154 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
