The c.624A>T (p.L208F) alteration is located in exon 8 (coding exon 8) of the PKHD1L1 gene. This alteration results from a A to T substitution at nucleotide position 624, causing the leucine (L) at amino acid position 208 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
