The c.509T>C (p.I170T) alteration is located in exon 6 (coding exon 5) of the SPOPL gene. This alteration results from a T to C substitution at nucleotide position 509, causing the isoleucine (I) at amino acid position 170 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
