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]
CCDC113 (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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 26, 2024The c.779A>T (p.Y260F) alteration is located in exon 7 (coding exon 5) of the PRSS54 gene. This alteration results from a A to T substitution at nucleotide position 779, causing the tyrosine (Y) at amino acid position 260 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
