The c.4019G>C (p.S1340T) alteration is located in exon 29 (coding exon 29) of the SCAPER gene. This alteration results from a G to C substitution at nucleotide position 4019, causing the serine (S) at amino acid position 1340 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
