Collection Method: clinical testing

The c.581G>A (p.R194H) alteration is located in exon 2 (coding exon 1) of the TSC22D4 gene. This alteration results from a G to A substitution at nucleotide position 581, causing the arginine (R) at amino acid position 194 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
