Collection Method: clinical testing

The c.1084C>T (p.P362S) alteration is located in exon 2 (coding exon 1) of the ZBTB45 gene. This alteration results from a C to T substitution at nucleotide position 1084, causing the proline (P) at amino acid position 362 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
