Genes affected
CABP5 (HGNC:13714): (calcium binding protein 5) The product of this gene belongs to a subfamily of calcium binding proteins, which share similarity to calmodulin. Calcium binding proteins are an important component of calcium mediated cellular signal transduction. Expression of this gene is retina-specific. The mouse homolog of this protein has been shown to express in the inner nuclear layer of the retina, suggested its role in neuronal functioning. The specific function of this gene is unknown.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.236A>T (p.N79I) alteration is located in exon 3 (coding exon 3) of the CABP5 gene. This alteration results from a A to T substitution at nucleotide position 236, causing the asparagine (N) at amino acid position 79 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
