Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.379G>A (p.V127I) alteration is located in exon 2 (coding exon 2) of the THUMPD1 gene. This alteration results from a G to A substitution at nucleotide position 379, causing the valine (V) at amino acid position 127 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
