Collection Method: clinical testing

The c.142G>A (p.A48T) alteration is located in exon 3 (coding exon 3) of the RAP1GDS1 gene. This alteration results from a G to A substitution at nucleotide position 142, causing the alanine (A) at amino acid position 48 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
