Ambry Genetics

Jan 19, 2024

The c.98G>C (p.S33T) alteration is located in exon 1 (coding exon 1) of the TRAPPC4 gene. This alteration results from a G to C substitution at nucleotide position 98, causing the serine (S) at amino acid position 33 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
