Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.15G>C (p.Q5H) alteration is located in exon 2 (coding exon 1) of the LCE3E gene. This alteration results from a G to C substitution at nucleotide position 15, causing the glutamine (Q) at amino acid position 5 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
