The c.1196C>A (p.T399N) alteration is located in exon 11 (coding exon 10) of the PTPN5 gene. This alteration results from a C to A substitution at nucleotide position 1196, causing the threonine (T) at amino acid position 399 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
