The c.334A>G (p.S112G) alteration is located in exon 4 (coding exon 4) of the RELL2 gene. This alteration results from a A to G substitution at nucleotide position 334, causing the serine (S) at amino acid position 112 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
