Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 17, 2024The c.646T>G (p.F216V) alteration is located in exon 6 (coding exon 5) of the PQLC1 gene. This alteration results from a T to G substitution at nucleotide position 646, causing the phenylalanine (F) at amino acid position 216 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
