Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.416A>T (p.N139I) alteration is located in exon 4 (coding exon 4) of the PKHD1L1 gene. This alteration results from a A to T substitution at nucleotide position 416, causing the asparagine (N) at amino acid position 139 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
