Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.718A>G (p.I240V) alteration is located in exon 9 (coding exon 9) of the PKHD1L1 gene. This alteration results from a A to G substitution at nucleotide position 718, causing the isoleucine (I) at amino acid position 240 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
