Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.53C>T (p.P18L) alteration is located in exon 3 (coding exon 1) of the CDC42SE1 gene. This alteration results from a C to T substitution at nucleotide position 53, causing the proline (P) at amino acid position 18 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
