Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.1348T>A (p.C450S) alteration is located in exon 10 (coding exon 9) of the PRPF39 gene. This alteration results from a T to A substitution at nucleotide position 1348, causing the cysteine (C) at amino acid position 450 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
