The c.587T>C (p.F196S) alteration is located in exon 4 (coding exon 4) of the PTPMT1 gene. This alteration results from a T to C substitution at nucleotide position 587, causing the phenylalanine (F) at amino acid position 196 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
