Genes affected
ZNF227 (HGNC:13020): (zinc finger protein 227) Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of transcription, DNA-templated. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
ZNF235 (HGNC:12866): (zinc finger protein 235) This gene product belongs to the zinc finger protein superfamily, members of which are regulatory proteins characterized by nucleic acid-binding zinc finger domains. The encoded protein is a member of the Kruppel family of zinc finger proteins, and contains Kruppel-associated box (KRAB) A and B domains and 15 tandemly arrayed C2H2-type zinc fingers. It is an ortholog of the mouse Zfp93 protein. This gene is located in a cluster of zinc finger genes on 19q13.2. [provided by RefSeq, Jul 2008]

The c.344C>T (p.S115F) alteration is located in exon 6 (coding exon 4) of the ZNF227 gene. This alteration results from a C to T substitution at nucleotide position 344, causing the serine (S) at amino acid position 115 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
