Collection Method: clinical testing

The c.220G>T (p.A74S) alteration is located in exon 3 (coding exon 2) of the STAMBPL1 gene. This alteration results from a G to T substitution at nucleotide position 220, causing the alanine (A) at amino acid position 74 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
