Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.500G>A (p.R167H) alteration is located in exon 4 (coding exon 1) of the SLC7A6 gene. This alteration results from a G to A substitution at nucleotide position 500, causing the arginine (R) at amino acid position 167 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
