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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 29, 2021The c.783G>C (p.W261C) alteration is located in exon 7 (coding exon 7) of the PRDM7 gene. This alteration results from a G to C substitution at nucleotide position 783, causing the tryptophan (W) at amino acid position 261 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
