The c.197C>G (p.T66R) alteration is located in exon 3 (coding exon 3) of the ZPLD1 gene. This alteration results from a C to G substitution at nucleotide position 197, causing the threonine (T) at amino acid position 66 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
