Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 27, 2023The c.409T>G (p.F137V) alteration is located in exon 5 (coding exon 4) of the PQLC1 gene. This alteration results from a T to G substitution at nucleotide position 409, causing the phenylalanine (F) at amino acid position 137 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
