The c.506A>T (p.H169L) alteration is located in exon 7 (coding exon 6) of the PACRGL gene. This alteration results from a A to T substitution at nucleotide position 506, causing the histidine (H) at amino acid position 169 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
