Genes affected
RCN2 (HGNC:9935): (reticulocalbin 2) The protein encoded by this gene is a calcium-binding protein located in the lumen of the ER. The protein contains six conserved regions with similarity to a high affinity Ca(+2)-binding motif, the EF-hand. This gene maps to the same region as type 4 Bardet-Biedl syndrome, suggesting a possible causative role for this gene in the disorder. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2012]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 30, 2022 | The c.794A>T (p.Q265L) alteration is located in exon 6 (coding exon 6) of the RCN2 gene. This alteration results from a A to T substitution at nucleotide position 794, causing the glutamine (Q) at amino acid position 265 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
