The c.211T>G (p.S71A) alteration is located in exon 4 (coding exon 3) of the RNFT2 gene. This alteration results from a T to G substitution at nucleotide position 211, causing the serine (S) at amino acid position 71 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
