Is Mitochondrial X-linked only?

By SWA

 Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function. Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
Is your mitochondrial DNA 100% from your mom?

Each of these mitochondria is coded for by a tiny amount of 'mitochondrial DNA'. Mitochondrial DNA makes up only 0.1% of the overall human genome and is passed down exclusively from mother to child.

What genes are found in mitochondrial DNA?

The mtDNA genes encode: 2 rRNAs, 22 tRNAs and 13 of 83 genes for respiratory chain subunits (MT-ATP6, MT-ATP8, MT-CO1, MT-CO2, MT-CO3, MT-CYB, MT-ND1, MT-ND2, MT-ND3, MT-ND4, MT-ND4L, MT-ND5, MT-ND6).

What is mitochondrial DNA genetically identical to?

A person's mitochondrial DNA sequence is shared with all of his or her maternal relatives, allowing a genetic match even with few surviving relatives. Mitochondrial DNA varies greatly between unrelated families, but it should be nearly identical among closely related individuals.

What does a girl inherit from her father?

Daughters get two X chromosomes, one from Mother and one from Father. So Daughter will inherit X-linked genes from her father as well as her mother. Examples of X-linked recessive disorders are hemophilia, red-green color blindness, and Wiskott-Aldrich syndrome.

What traits are inherited from mother only?

What does a man inherit from his mother?

Males inherit one X chromosome from their mother and one Y chromosome from their father, making them XY. Females, on the other hand, inherit an X chromosome from both parents, making them XX. This inheritance means that all of the genetic material inside a male's X chromosome is maternally derived.

Which trait can never be passed from father to son?

X chromosomes linked diseases are inherited with inheritance of X chromosome. Since father transmits its X chromosome to the daughters, not to son, X linked diseases cannot be passed from a father to son. This makes option A correct.

The list of inherited genes is long and mostly fun to explore.

Toxic Skin Condition Post-mRNA COVID-19 Vaccination

Identifying Severe Skin Conditions Post-Vaccination Following administration of the BioNTech mRNA vaccine, a small subset of individuals may develop severe and complex reactions. These reactions are often misdiagnosed or misunderstood due to their rarity and diverse presentation. This essay examines a case characterized by severe skin conditions, systemic symptoms, and complications such as hypercalcemia and crystal formation. It highlights the need for accurate diagnosis, holistic management, and increased awareness of these rare but significant vaccine-related adverse events. Initial Symptoms and Misdiagnoses Severe symptoms began shortly after the first dose of the BioNTech vaccine, initially presenting as petechiae, diagnosed by a rheumatologist. However, following the second dose, symptoms rapidly escalated, resulting in intense burning pain and thinning of the skin. The skin on the legs and thighs became paper-thin and could tear with the slightest touch, with the affected area e...

Dysferlin Protein: Key Roles, Genetic Locations

By SWA

The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

By SWA

Today, I understand why Spinal Muscular Atrophy (SMA) received little attention, particularly in the mid-50s. This complex and debilitating genetic illness was poorly understood, and patients' symptoms were often minimized or even dismissed. For more information, please visit the Spinal Muscular Atrophy (SMA) page on MalaCards . Even now, many neurologists lack detailed knowledge of SMA, and comprehensive examinations mentioned in research are rarely pursued. In 2008, while investigating permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II. However, surgery in 2009 brought no improvement. In 2010, a DNA test showed a genetic marker in the ACTN3 gene: https://www.malacards.org/search/results?q=ACTN3%20gene%20and%20Spinal%20Muscular%20Atrophy%20(SMA) A 2015 MRI revealed ankylosing spondylitis, multiple Tarlov cysts, stenosis at L4 and L5, spinal canal narrowing, and widespread degenerative changes. Surgery on L4 and L5 ...
