Genes affected

TRERF1 (HGNC:18273): (transcriptional regulating factor 1) This gene encodes a zinc-finger transcriptional regulating protein which interacts with CBP/p300 to regulate the human gene CYP11A1. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2014]

TRERF1 Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

Collection Method: clinical testing

The c.3425C>T (p.P1142L) alteration is located in exon 18 (coding exon 14) of the TRERF1 gene. This alteration results from a C to T substitution at nucleotide position 3425, causing the proline (P) at amino acid position 1142 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
