Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2022The c.511G>C (p.A171P) alteration is located in exon 3 (coding exon 3) of the THUMPD1 gene. This alteration results from a G to C substitution at nucleotide position 511, causing the alanine (A) at amino acid position 171 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
