Collection Method:clinical testing

The c.58T>C (p.W20R) alteration is located in exon 2 (coding exon 1) of the MORN4 gene. This alteration results from a T to C substitution at nucleotide position 58, causing the tryptophan (W) at amino acid position 20 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
