Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2023The c.1016A>G (p.K339R) alteration is located in exon 8 (coding exon 7) of the PRPF39 gene. This alteration results from a A to G substitution at nucleotide position 1016, causing the lysine (K) at amino acid position 339 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
