Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.883G>C (p.D295H) alteration is located in exon 6 (coding exon 6) of the THUMPD2 gene. This alteration results from a G to C substitution at nucleotide position 883, causing the aspartic acid (D) at amino acid position 295 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
