Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2022The c.416A>G (p.Q139R) alteration is located in exon 5 (coding exon 4) of the PQLC1 gene. This alteration results from a A to G substitution at nucleotide position 416, causing the glutamine (Q) at amino acid position 139 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
