Genotype/Phenotype analysis of a photoreceptor-specific ATP-binding cassette transporter gene, ABCR, in Stargardt disease.
Analysis of ABCA4 variants in 150 families with Stargardt disease. Most of which were of northern or central European ancestry. For comparison, 220 racially matched individuals with no personal history or known family history of STGD served as controls (Anderson et al. 1995; Allikmets et al. 1997b).

Mutation scanning and direct DNA sequencing of all 50 exons of ABCR were completed for 150 families segregating recessive Stargardt disease (STGD1). ABCR variations were identified in 173 (57%) disease chromosomes, the majority of which represent missense amino acid substitutions. These ABCR variants were not found in 220 unaffected control individuals (440 chromosomes) but do cosegregate with the disease in these families with STGD1, and many occur in conserved functional domains. Missense amino acid substitutions located in the amino terminal one-third of the protein appear to be associated with earlier onset of the disease and may represent misfolding alleles. The two most common mutant alleles, G1961E and A1038V, each identified in 16 of 173 disease chromosomes, composed 18.5% of mutations identified. G1961E has been associated previously, at a statistically significant level in the heterozygous state, with age-related macular degeneration (AMD). Clinical evaluation of these 150 families with STGD1 revealed a high frequency of AMD in first- and second-degree relatives. These findings support the hypothesis that compound heterozygous ABCR mutations are responsible for STGD1 and that some heterozygous ABCR mutations may enhance susceptibility to AMD.

CasePresentingHPOs: The essential and defining features of STGD were (1) pedigrees with at least one living affected individual compatible with autosomal recessive inheritance; (2) an ophthalmoscopically characteristic retinal disorder in families with both parents living; (3) bilateral central visual loss with both “beaten metal” elliptical foveal dystrophy and temporal pallor of the optic discs, documented by retinal color photography, with or without yellow-pigment epithelial flecks in the macular and/or retinal “near periphery”; and (4) the characteristic fluorescein angiographic feature of a dark choroid (Blacharski 1988).
CaseHPOFreeText:
CaseNotHPOs:
CaseNotHPOFreeText: (1) evidence of autosomal dominant inheritance; (2) any history of night blindness, loss of peripheral vision, or "retinitis pigmentosa"; (3) cataracta complicata or cells in the vitreous; (4) substantially abnormal electroretinographic or electrooculographic responses; (5) no fluorescein angiography performed or no dark choroid documented; (6) neurological disease (including loss of cognition or seizures); 7) drug exposures (especially to antimalarial and agents known to cause crystalline retinopathies); or (8) any "atypical" maculopathies in which a unique diagnosis of STGD could not be established.

Amounts of A2E in the eyes of Abca4PV/PV, Abca4−/− and WT mice at the ages of 1, 3, 6, 12 and 15 months were quantified by reverse-phase high-performance liquid chromatography (HPLC) (Fig. 9B). Mice were raised under a regular 12-h light (∼10 lux)/12-h dark cycle. Age-dependent A2E accumulation was noted in all genotypes, with Abca4PV/PV and Abca4−/− mice accumulating about 5-fold more A2E than WT mice. No statistically significant differences in A2E accumulation were found between Abca4PV/PV and Abca4−/− animals.
Autofluorescence and A2E production was measured in transgenic mice and showed loss of function of ABCA4 protein indicating that this variant impacts protein function (PS3; PMIDs).

Screening of reported pathogenic variants in ABCA4 for Stargardt (STGD) The disease prevalence of STGD is estimated as 1 in 10000 individuals4. It has been estimated that about 70% of STGD patients carry variants in ABCA45. Therefore, this represents the scenario of a recessive disease with a relatively homogeneous genetic cause.

https://en.wikipedia.org/wiki/Shmita
During shmita, the land is left to lie fallow and all agricultural activity, including plowing, planting, pruning and harvesting, is forbidden by halakha (Jewish law).
The sabbath year (shmita; Hebrew: שמיטה, literally "release"), also called the sabbatical year or shǝvi'it (שביעית, literally "seventh"), or "Sabbath of The Land", is the seventh year of the seven-year agricultural cycle mandated by the Torah in the Land of Israel and is observed in Judaism.
The phrase "Rule 34" was coined from an August 13, 2003 webcomic captioned, "Rule #34 There is porn of it. No exceptions." The comic was drawn by TangoStari (Peter Morley-Souter) to depict his shock at seeing Calvin and Hobbes parody porn.[1][2]
With the exception of the blues, the rhythm changes progression is probably the mostimportant chord progression in jazz. The term “rhythm changes” refers to a 32-bar AABAform based on the harmonic structure of “I Got Rhythm” by George and Ira Gershwin.The song appeared in the Aarons and Freedley production Girl Crazy (1930) andoriginally featured a 34-bar AABA form with a two-bar extension in the last A section.The two-bar extension was eventually cut and the chord changes of the last A sectionreplicated those from the second A. A newly composed line based on the rhythm changesprogression is known as a contrafact. The enormous popularity of rhythm changes hasbeen well documented by an ever-increasing number of composed contrafacts andrecordings

Results for individual PALB2 variants were normalized relative to WT-PALB2 and the p.Tyr551ter (p.Y551X) truncating variant on a 1:5 scale with the fold change in GFP-positive cells for WT set at 5.0 and fold change GFP-positive cells for p.Y551X set at 1.0. The p.L24S (c.71T>C), p.L35P (c.104T>C), p.I944N (c.2831T>A), and p.L1070P (c.3209T>C) variants and all protein-truncating frame-shift and deletion variants tested were deficient in HDR activity, with normalized fold change <2.0 (approximately 40% activity) (Fig. 1a).

In order to protect local interests, and to prevent sectional jealousies, it was found requisite that the three great divisions into which British North America is separated, should be represented in the Upper House on the principle of equality. There are three great sections, having different interests, in this proposed Confederation.

To the Upper House is to be confided the protection of sectional interests ; therefore is it that the three great divisions are there equally represented, for the purpose of defending such interests against the combinations of majorities in the Assembly.

But the very essence of our compact is that the union shall be federal and not legislative. Our Lower Canada friends have agreed to give us representation by population in the Lower House, on the express condition that they shall have equality in the Upper House. On no other condition could we have advanced a step ; and, for my part, I am quite willing they should have it. In maintaining the existing sectional boundaries and handing over the control of local matters to local bodies, we recognize, to a certain extent, a diversity of interests ; and it was quite natural that the protection for those interests, by equality in the Upper Chamber, should be demanded by the less numerous provinces.

Gentlemen, if the principle is good in one case, it is good in another ; let us make the Speaker elective. No, no, they said, that will not do ; that is republicanism.
§.34 of the Constitution Act, 1867.
The Speaker of the Legislative Council is also to be appointed by the Crown, this is another step backwards, and a little piece of patronage for the Government. We have heard in a speech lately delivered in Prince Edward Island or New Brunswick, I forget which, of the allurements offered to the delegates while here in the shape of prospective appointments as judges of the Court of Appeal, Speaker of the Legislative Council, and local governors
