Collection Method: clinical testing

The c.62C>T (p.P21L) alteration is located in exon 1 (coding exon 1) of the LCE1F gene. This alteration results from a C to T substitution at nucleotide position 62, causing the proline (P) at amino acid position 21 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
