Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2023The c.435G>C (p.K145N) alteration is located in exon 6 (coding exon 5) of the PAPLN gene. This alteration results from a G to C substitution at nucleotide position 435, causing the lysine (K) at amino acid position 145 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
