Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.1280A>G (p.N427S) alteration is located in exon 10 (coding exon 10) of the THUMPD2 gene. This alteration results from a A to G substitution at nucleotide position 1280, causing the asparagine (N) at amino acid position 427 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
