Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.787G>A (p.V263M) alteration is located in exon 6 (coding exon 5) of the PQLC1 gene. This alteration results from a G to A substitution at nucleotide position 787, causing the valine (V) at amino acid position 263 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
