Genes affected
LRIT1 (HGNC:23404): (leucine rich repeat, Ig-like and transmembrane domains 1) Predicted to be integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]
RGR (HGNC:9990): (retinal G protein coupled receptor) This gene encodes a putative retinal G-protein coupled receptor. The gene is a member of the opsin subfamily of the 7 transmembrane, G-protein coupled receptor 1 family. Like other opsins which bind retinaldehyde, it contains a conserved lysine residue in the seventh transmembrane domain. The protein acts as a photoisomerase to catalyze the conversion of all-trans-retinal to 11-cis-retinal. The reverse isomerization occurs with rhodopsin in retinal photoreceptor cells. The protein is exclusively expressed in tissue adjacent to retinal photoreceptor cells, the retinal pigment epithelium and Mueller cells. This gene may be associated with autosomal recessive and autosomal dominant retinitis pigmentosa (arRP and adRP, respectively). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.1840G>A (p.G614R) alteration is located in exon 4 (coding exon 4) of the LRIT1 gene. This alteration results from a G to A substitution at nucleotide position 1840, causing the glycine (G) at amino acid position 614 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
