Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.706C>T (p.L236F) alteration is located in exon 6 (coding exon 3) of the SLC7A6 gene. This alteration results from a C to T substitution at nucleotide position 706, causing the leucine (L) at amino acid position 236 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
