Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.4G>A (p.G2R) alteration is located in exon 1 (coding exon 1) of the SEBOX gene. This alteration results from a G to A substitution at nucleotide position 4, causing the glycine (G) at amino acid position 2 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
