Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 07, 2022The c.179T>A (p.L60H) alteration is located in exon 2 (coding exon 1) of the THUMPD3 gene. This alteration results from a T to A substitution at nucleotide position 179, causing the leucine (L) at amino acid position 60 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
