Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.410T>C (p.L137S) alteration is located in exon 5 (coding exon 4) of the PQLC2 gene. This alteration results from a T to C substitution at nucleotide position 410, causing the leucine (L) at amino acid position 137 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
