not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.662G>A (p.G221D) alteration is located in exon 8 (coding exon 8) of the PKHD1L1 gene. This alteration results from a G to A substitution at nucleotide position 662, causing the glycine (G) at amino acid position 221 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
