Collection Method: clinical testing

The c.548C>T (p.P183L) alteration is located in exon 1 (coding exon 1) of the LRRC14B gene. This alteration results from a C to T substitution at nucleotide position 548, causing the proline (P) at amino acid position 183 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
