Genes affected

LRRC19 (HGNC:23379): (leucine rich repeat containing 19) Predicted to enable signaling receptor activity. Acts upstream of or within positive regulation of NIK/NF-kappaB signaling. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

LRRC19 links:

IFT74 (HGNC:21424): (intraflagellar transport 74) This gene encodes a core intraflagellar transport (IFT) protein which belongs to a multi-protein complex involved in the transport of ciliary proteins along axonemal microtubules. IFT proteins are found at the base of the cilium as well as inside the cilium, where they assemble into long arrays between the ciliary base and tip. This protein, together with intraflagellar transport protein 81, binds and transports tubulin within cilia and is required for ciliogenesis. Naturally occurring mutations in this gene are associated with amyotrophic lateral sclerosis--frontotemporal dementia and Bardet-Biedl Syndrome. [provided by RefSeq, Mar 2017]

The c.827T>G (p.V276G) alteration is located in exon 5 (coding exon 4) of the LRRC19 gene. This alteration results from a T to G substitution at nucleotide position 827, causing the valine (V) at amino acid position 276 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
