Genes affected

CFAP99 (HGNC:51180): (cilia and flagella associated protein 99) Predicted to be located in motile cilium. [provided by Alliance of Genome Resources, Apr 2022]

CFAP99 links:

RNF4 (HGNC:10067): (ring finger protein 4) The protein encoded by this gene contains a RING finger motif and acts as a transcription regulator. This protein has been shown to interact with, and inhibit the activity of, TRPS1, a transcription suppressor of GATA-mediated transcription. Transcription repressor ZNF278/PATZ is found to interact with this protein, and thus reduce the enhancement of androgen receptor-dependent transcription mediated by this protein. Studies of the mouse and rat counterparts suggested a role of this protein in spermatogenesis. A pseudogene of this gene is found on chromosome 1.[provided by RefSeq, Jul 2010]

The c.1933G>A (p.A645T) alteration is located in exon 16 (coding exon 15) of the CFAP99 gene. This alteration results from a G to A substitution at nucleotide position 1933, causing the alanine (A) at amino acid position 645 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
