The c.4291G>C (p.E1431Q) alteration is located in exon 20 (coding exon 20) of the CASKIN1 gene. This alteration results from a G to C substitution at nucleotide position 4291, causing the glutamic acid (E) at amino acid position 1431 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
