Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.17C>G (p.P6R) alteration is located in exon 1 (coding exon 1) of the SETD1B gene. This alteration results from a C to G substitution at nucleotide position 17, causing the proline (P) at amino acid position 6 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
