Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001193282.4(CFAP99):c.1676A>C(p.Lys559Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000554 in 1,462,200 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 8/12 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K559E) has been classified as Uncertain significance.

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.1676A>C (p.K559T) alteration is located in exon 15 (coding exon 14) of the CFAP99 gene. This alteration results from a A to C substitution at nucleotide position 1676, causing the lysine (K) at amino acid position 559 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
