Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_153376.3(CFAP184):​c.524C>T​(p.Thr175Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T175R) has been classified as Uncertain significance.

Genes affected

CFAP184 (HGNC:26900): (cilia and flagella associated protein 184) Predicted to be involved in cilium assembly. Predicted to be active in axoneme and ciliary basal body. [provided by Alliance of Genome Resources, Apr 2022]

TADA2B (HGNC:30781): (transcriptional adaptor 2B) TADA2B functions as a transcriptional adaptor protein that potentiates transcription through coordination of histone acetyltransferase (HAT) activity and by linking activation factors to basal transcriptional machinery (Barlev et al., 2003 [PubMed 12972612]).[supplied by OMIM, Apr 2010]

ENSG00000245748 (HGNC:58725):

LOC100129931 (HGNC:):

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.072339654).
