Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.92G>A (p.R31K) alteration is located in exon 2 (coding exon 2) of the THAP2 gene. This alteration results from a G to A substitution at nucleotide position 92, causing the arginine (R) at amino acid position 31 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
