The c.2198C>A (p.S733Y) alteration is located in exon 6 (coding exon 6) of the ZNF827 gene. This alteration results from a C to A substitution at nucleotide position 2198, causing the serine (S) at amino acid position 733 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
