Collection Method: clinical testing

The c.746G>A (p.R249Q) alteration is located in exon 3 (coding exon 2) of the MSANTD4 gene. This alteration results from a G to A substitution at nucleotide position 746, causing the arginine (R) at amino acid position 249 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
