Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2024The c.215T>C (p.L72P) alteration is located in exon 3 (coding exon 2) of the PQLC2 gene. This alteration results from a T to C substitution at nucleotide position 215, causing the leucine (L) at amino acid position 72 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
