Genes affected

PRSS54 (HGNC:26336): (serine protease 54) This gene encodes a putative serine-type endopeptidase containing the peptidase S1 domain. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

CFAP263 (HGNC:25002): (cilia and flagella associated protein 263) Involved in cilium assembly. Located in centriolar satellite and ciliary basal body. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP7: Synonymous conserved (PhyloP=-0.403 with no splicing effect.
