The c.1083G>T (p.E361D) alteration is located in exon 10 (coding exon 9) of the PKNOX1 gene. This alteration results from a G to T substitution at nucleotide position 1083, causing the glutamic acid (E) at amino acid position 361 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
