Genes affected

TRIML1 (HGNC:26698): (tripartite motif family like 1) The protein encoded by this gene is a tripartite motif family protein with similarities to E3 ubiquitin-protein ligases. While the function of the encoded protein has not been determined, the orthologous protein in mouse has been shown to bind ubiquitin-specific protease 5 and is involved in the blastocyst development stage.

Collection Method: clinical testing

The c.148C>T (p.P50S) alteration is located in exon 1 (coding exon 1) of the TRIML1 gene. This alteration results from a C to T substitution at nucleotide position 148, causing the proline (P) at amino acid position 50 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
