Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.74A>G (p.Q25R) alteration is located in exon 3 (coding exon 2) of the PAPLN gene. This alteration results from a A to G substitution at nucleotide position 74, causing the glutamine (Q) at amino acid position 25 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
