Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 17, 2023The c.620C>T (p.T207I) alteration is located in exon 1 (coding exon 1) of the TSC22D2 gene. This alteration results from a C to T substitution at nucleotide position 620, causing the threonine (T) at amino acid position 207 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
