Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1391A>G (p.K464R) 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 1391, causing the lysine (K) at amino acid position 464 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
