Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.470C>A (p.T157N) alteration is located in exon 5 (coding exon 5) of the PKHD1L1 gene. This alteration results from a C to A substitution at nucleotide position 470, causing the threonine (T) at amino acid position 157 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
