Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.35C>A (p.P12H) alteration is located in exon 2 (coding exon 1) of the LCE2D gene. This alteration results from a C to A substitution at nucleotide position 35, causing the proline (P) at amino acid position 12 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
