  • 功能：
    Visual signal transduction is mediated by a G-protein coupled cascade using cGMP as second messenger. This protein can be activated by cyclic GMP which leads to an opening of the cation channel and thereby causing a depolarization of cone photoreceptors. Induced a flickering channel gating, weakened the outward rectification in the presence of extracellular calcium, increased sensitivity for L-cis diltiazem and enhanced the cAMP efficacy of the channel when coexpressed with CNGB3. Essential for the generation of light-evoked electrical responses in the red-, green- and blue sensitive cones.

    1. Here, we report the identification of a novel isoform of human CNGA3 resulting from an in-frame alternative translation initiation site (TIS) 154 bp downstream of the first TIS. Results suggest that the short isoform is not able to compensate for the loss of the long isoform leaving the biological role of this variant unclear. PMID: 29499183
    2. The c.1618G>A, p.Gly540Ser substitution in CNGA3 was identified as the causative mutation for a novel form of ACHM in Awassi sheep. Gene augmentation therapy restored vision in the affected sheep. This novel mutation provides a large-animal model that is valid for most human CNGA3 ACHM patients; the majority of them carry missense rather than premature-termination mutations. PMID: 28282490
    3. Four mutations (c.1682G>A;p.G561E, c.139C>T;p.Q47*, c.784G>C;p.A282P, c.1116delC;p.V373*) represent novel mutations of CNGA3 reported herein for the first time in patients with Achromatopsia. PMID: 28159970
    4. The two novel mutations found in the CNGA3 gene, c.997_998delGA and p.M424V, can cause complete achromatopsia. The vision of the patient was stationary until the third decade of life although the FAF was altered at the age of 22 years. PMID: 27040408

    6. Among Israeli and Palestinian patients, CNGA3 mutations are the leading cause of achromatopsia. Retinal structural results support the candidacy of CNGA3 ACHM for clinical trials for therapy of cone photoreceptors. PMID: 25616768
    7. CNGA3 mutation is the most frequent cause of achromatopsia in this cohort of patients. Ten novel mutations were identified in CNGA3. PMID: 25637600

    10. CNGA3 alternative splicing may have evolved, in part, to tune the interactions between cone CNG channels and membrane-bound phosphoinositides. PMID: 24675082
    11. The majority (n = 12) of patients were either homozygotes or compound heterozygotes for known achromatopsia alleles, two in CNGB3 (p.T383fsX and p.T296YfsX9) and three in CNGA3 (p.R283Q, p.R427C and p.L527R). PMID: 23362848
    12. The biochemical feedback regulation of CNGA3 mutations in color blindness is reported. PMID: 23677796
    13. These studies support a model in which intersubunit interactions control the sensitivity of cone CNG channels to regulation by phosphoinositides. PMID: 23552282
    14. in a set of consanguineous patient families with Leber congenital amaurosis study identified five putative disease-causing mutations, including four novel alleles, in six families; These five mutations are located in four genes, ALMS1, IQCB1, CNGA3, and MYO7A PMID: 21901789
    15. observed a nuclear translocation of apoptosis-inducing factor (AIF) and endonuclease G in CNGA3(-/-)/Nrl(-/-) and CNGB3(-/-)/Nrl(-/-) retinas, implying a mitochondrial insult in the endoplasmic reticulum stress-activated cell death process PMID: 22493484
    16. We describe a novel S4 motif mutation of CNGA3 in a Pakistani family. PMID: 21912902
    17. Two compound heterozygous mutations were identified in CNGA3 of this patient, c.829C>T p.R277C and c.1580T>G p.L527R; they were not observed in the normal population and cosegregated with the phenotype of achromatopsia in the patient's family. PMID: 21911670

    20. Data identified three novel mutations in the pore-forming region of CNGA3 (L363P, G367V, and E376K) in achromatopsia patients, and reduced macroscopic currents for channels with the mutations G367V, and E376K. PMID: 20506298
    21. haplotype analysis of c.1585G>A-bearing chromosomes from Middle Eastern and European origins showed a shared Muslim-Jewish haplotype, different from that detected in Europeans, indicating a recurrent mutation with a Jewish-Muslim founder effect PMID: 20549516
    22. Genetic analysis of two Pakistani families with retinal disease enabled the establishment of the correct diagnosis of achromatopsia. Two novel mutations were identified in CNGA3 and CNGB3 that are both specifically expressed in cone photoreceptors. PMID: 20454696
    23. Our data indicate that these genes are involved in a broader spectrum of cone dysfunction, and it remains intriguing why initial cone function can be spared despite similar gene defects. PMID: 20079539
