Collection Method:clinical testing

The c.157G>T (p.A53S) alteration is located in exon 1 (coding exon 1) of the VMAC gene. This alteration results from a G to T substitution at nucleotide position 157, causing the alanine (A) at amino acid position 53 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
