The c.52A>G (p.T18A) alteration is located in exon 1 (coding exon 1) of the RANBP3L gene. This alteration results from a A to G substitution at nucleotide position 52, causing the threonine (T) at amino acid position 18 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
