Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1202G>A (p.R401H) alteration is located in exon 5 (coding exon 4) of the SLC16A8 gene. This alteration results from a G to A substitution at nucleotide position 1202, causing the arginine (R) at amino acid position 401 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
