Collection Method: clinical testing

The c.455T>C (p.M152T) alteration is located in exon 5 (coding exon 5) of the RGSL1 gene. This alteration results from a T to C substitution at nucleotide position 455, causing the methionine (M) at amino acid position 152 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
