The c.245C>T (p.T82M) alteration is located in exon 1 (coding exon 1) of the PYDC2 gene. This alteration results from a C to T substitution at nucleotide position 245, causing the threonine (T) at amino acid position 82 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
