The c.185T>G (p.L62R) alteration is located in exon 2 (coding exon 1) of the ZSCAN16 gene. This alteration results from a T to G substitution at nucleotide position 185, causing the leucine (L) at amino acid position 62 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
