Genes affected

RNF148 (HGNC:22411): (ring finger protein 148) Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in ubiquitin-dependent protein catabolic process. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus; endoplasmic reticulum; and late endosome. [provided by Alliance of Genome Resources, Apr 2022]

RNF148 links:

CADPS2 (HGNC:16018): (calcium dependent secretion activator 2) This gene encodes a member of the calcium-dependent activator of secretion (CAPS) protein family, which are calcium binding proteins that regulate the exocytosis of synaptic and dense-core vesicles in neurons and neuroendocrine cells. Mutations in this gene may contribute to autism susceptibility. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2009]

Ambry Genetics

Dec 19, 2023

The c.720A>C (p.Q240H) alteration is located in exon 1 (coding exon 1) of the RNF148 gene. This alteration results from a A to C substitution at nucleotide position 720, causing the glutamine (Q) at amino acid position 240 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
