Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.1028C>A (p.T343N) alteration is located in exon 11 (coding exon 10) of the PAPD4 gene. This alteration results from a C to A substitution at nucleotide position 1028, causing the threonine (T) at amino acid position 343 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
