Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.763T>C (p.F255L) alteration is located in exon 5 (coding exon 5) of the THAP9 gene. This alteration results from a T to C substitution at nucleotide position 763, causing the phenylalanine (F) at amino acid position 255 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
