Genes affected

PRDM7 (HGNC:9351): (PR/SET domain 7) This gene encodes a member of a family of proteins that may have roles in transcription and other nuclear processes. The encoded protein contains a KRAB (Kruppel-associated box) domain -A box and a SET (Su(var)3-9, Enhancer-of-zeste, Trithorax) domain and may function as a histone methyltransferase.

The c.407C>T (p.T136M) alteration is located in exon 5 (coding exon 5) of the PRDM7 gene. This alteration results from a C to T substitution at nucleotide position 407, causing the threonine (T) at amino acid position 136 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
