Collection Method: clinical testing

The c.440G>A (p.R147H) alteration is located in exon 3 (coding exon 3) of the SEBOX gene. This alteration results from a G to A substitution at nucleotide position 440, causing the arginine (R) at amino acid position 147 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
