Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 31, 2023The c.199G>A (p.D67N) alteration is located in exon 3 (coding exon 2) of the PQLC2 gene. This alteration results from a G to A substitution at nucleotide position 199, causing the aspartic acid (D) at amino acid position 67 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
