Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.432A>T (p.Q144H) alteration is located in exon 3 (coding exon 3) of the USP39 gene. This alteration results from a A to T substitution at nucleotide position 432, causing the glutamine (Q) at amino acid position 144 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
