Enyeart JJ, Enyeart JA. Adrenal fasciculata cells express T-type and rapidly and slowly activating L-type Ca channels that regulate cortisol secretion. Am J Physiol Cell Physiol 308: C899–C918, 2015. First published March 18, 2015; doi:10.1152/ajpcell.00002.2015.—In whole cell patch-clamp recordings, we characterized the L-type Ca currents in bovine adrenal zona fasciculata (AZF) cells and expl...

Maturation arrest (MA) refers to failure of germ cell development leading to clinical nonobstructive azoospermia. Although the azoospermic factor (AZF) region of the human Y chromosome is clearly implicated in some cases, thus far very little is known about which individual Y-chromosome genes are important for complete male germ cell development. We sought to identify single genes on the Y chro...

Genetic lesions causing human male infertility are manifold. Besides gross chromosomal aneuploidies and rearrangements, microdeletions and single gene defects can interfere with male fertility. Male fertility is not only dependent on genes controlling the male germ line but also on genes of the networks functional for male gonad development and male somatic development, respectively. It is popu...

Mowat-Wilson syndrome (MWS) is a rare autosomal dominant characterized by dysmorphic features, mental retardation, and congenital heart disease (CHD). MWS results from microdeletions of chromosome 2q23 or de novo SNVs involving the <i>ZEB2</i> gene. Here, we report on an Egyptian patient diagnosed chromosomal microarray (CMA). A 1-year-old male child was referred to CHD clinic, Nati...

We determined the association of androgen receptor (AR) (CAG)n lengths among fertile and infertile males and offspring conceived by intracytoplasmic sperm injection (ICSI). Assessment of (CAG)n repeats in the AR was performed in a Caucasian population by gene sequencing in fertile men (n=13), infertile men (n=64), boys conceived after ICSI (n=21), and boys conceived naturally (n=11). In the AZF...

We have created a human chromosomal map of the location known and candidate genes involved in primary lymphedema (PLE). This should facilitate further discovery provide basis for understanding microdeletions which cause lymphedema.

Deletions of the azoospermia factor (AZF) regions of the Y chromosome are associated with severe spermatogenic failure and represent the most frequent molecular genetic cause of azoospermia and severe oligozoospermia. The exact role of the candidate AZF genes is largely unknown due to both the extreme rarity of naturally occurring AZF gene-specific mutations and the lack of functional assays. H...
