Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.664C>T (p.P222S) alteration is located in exon 4 (coding exon 3) of the THUMPD3 gene. This alteration results from a C to T substitution at nucleotide position 664, causing the proline (P) at amino acid position 222 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
