The c.1093T>G (p.C365G) alteration is located in exon 4 (coding exon 3) of the ZSCAN21 gene. This alteration results from a T to G substitution at nucleotide position 1093, causing the cysteine (C) at amino acid position 365 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
