The c.50C>T (p.T17I) alteration is located in exon 1 (coding exon 1) of the RSL1D1 gene. This alteration results from a C to T substitution at nucleotide position 50, causing the threonine (T) at amino acid position 17 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
