Genes affected
CNPY4 (HGNC:28631): (canopy FGF signaling regulator 4) Predicted to enable signaling receptor binding activity. Involved in positive regulation of protein localization to plasma membrane. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]
TAF6 (HGNC:11540): (TATA-box binding protein associated factor 6) Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals. TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors or TAFs. TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation. This gene encodes one of the smaller subunits of TFIID that binds weakly to TBP but strongly to TAF1, the largest subunit of TFIID. Alternative splicing results in multiple transcript variants.

The c.7C>T (p.P3S) alteration is located in exon 1 (coding exon 1) of the CNPY4 gene. This alteration results from a C to T substitution at nucleotide position 7, causing the proline (P) at amino acid position 3 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
