Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.97C>T (p.R33W) alteration is located in exon 2 (coding exon 1) of the MEIG1 gene. This alteration results from a C to T substitution at nucleotide position 97, causing the arginine (R) at amino acid position 33 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
