Dec 02, 2024

The c.365C>T (p.T122I) alteration is located in exon 7 (coding exon 6) of the PARP8 gene. This alteration results from a C to T substitution at nucleotide position 365, causing the threonine (T) at amino acid position 122 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
