The c.874G>A (p.A292T) alteration is located in exon 5 (coding exon 5) of the ZKSCAN4 gene. This alteration results from a G to A substitution at nucleotide position 874, causing the alanine (A) at amino acid position 292 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
