Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.700C>T (p.R234W) alteration is located in exon 2 (coding exon 1) of the TSC22D4 gene. This alteration results from a C to T substitution at nucleotide position 700, causing the arginine (R) at amino acid position 234 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
