Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.131C>T (p.P44L) alteration is located in exon 2 (coding exon 2) of the TSTD1 gene. This alteration results from a C to T substitution at nucleotide position 131, causing the proline (P) at amino acid position 44 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
