The c.706G>A (p.G236S) alteration is located in exon 4 (coding exon 3) of the SYNDIG1L gene. This alteration results from a G to A substitution at nucleotide position 706, causing the glycine (G) at amino acid position 236 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
