The c.2741C>T (p.P914L) alteration is located in exon 7 (coding exon 7) of the ZKSCAN2 gene. This alteration results from a C to T substitution at nucleotide position 2741, causing the proline (P) at amino acid position 914 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
