Collection Method:clinical testing

The c.32C>T (p.P11L) alteration is located in exon 1 (coding exon 1) of the RBM42 gene. This alteration results from a C to T substitution at nucleotide position 32, causing the proline (P) at amino acid position 11 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
