The c.155C>T (p.T52I) alteration is located in exon 2 (coding exon 1) of the RRAD gene. This alteration results from a C to T substitution at nucleotide position 155, causing the threonine (T) at amino acid position 52 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
