Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.661C>T (p.P221S) alteration is located in exon 6 (coding exon 4) of the KIAA1841 gene. This alteration results from a C to T substitution at nucleotide position 661, causing the proline (P) at amino acid position 221 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
