Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.106C>T (p.L36F) alteration is located in exon 4 (coding exon 1) of the TMEM125 gene. This alteration results from a C to T substitution at nucleotide position 106, causing the leucine (L) at amino acid position 36 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
