Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.1522A>G (p.I508V) alteration is located in exon 5 (coding exon 5) of the THAP9 gene. This alteration results from a A to G substitution at nucleotide position 1522, causing the isoleucine (I) at amino acid position 508 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
