WebThe 46 chromosomes of a human cell are organized into 23 pairs, and the two members of each pair are said to be homologues of one another (with the slight exception of the X and Y chromosomes; see below). Human sperm and eggs, which have only one homologous chromosome from each pair, are said to be haploid ( 1n ).

WebMotivated by its biologic premise, reports from animal models , human sequencing case reports [15,16,18,19], and our previous finding that found only 2.9% of US patients with NS had a monogenic form of disease , we hypothesized that a proportion of the heritability of NS may result from protein-altering risk alleles within Mendelian NS genes ... WebThe short answer is that an allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles.
