The c.282T>A (p.H94Q) alteration is located in exon 3 (coding exon 3) of the PKHD1L1 gene. This alteration results from a T to A substitution at nucleotide position 282, causing the histidine (H) at amino acid position 94 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
