Silver–Russell dwarfism, also called Silver–Russell syndrome (SRS) or Russell–Silver syndrome (RSS) is a growth disorder occurring in approximately 1/50,000 to 1/100,000 births. In the United States it is usually referred to as Russell–Silver syndrome, and Silver–Russell syndrome elsewhere. It is one of 200 types of dwarfism and one of five types of primordial dwarfism and is one of the few forms that is considered treatable in some cases.
- Often small for gestational age (SGA) at birth (birth weight less than 2.8 kg)
- Feeding problems: the baby is uninterested in feeding and takes only small amounts with difficulty

- Triangular shaped face with a small jaw and a pointed chin that tends to lessen slightly with age. The mouth tends to curve down
- A blue tinge to the whites of the eyes in younger children
- Head circumference may be of normal size and disproportionate to a small body size
- Wide and late-closing fontanelle
- Body asymmetry: one side of the body grows more slowly than the other
- Continued poor growth with no "catch up" into the normal centile lines on growth chart
- Precocious puberty (occasionally)
- Low muscle tone
- Gastroesophageal reflux disease

In 2016 Nathan's diagnosis of Russell Silver Syndrome was taken away. He is currently and ongoingly going through extensive chromosome and genetic testing in hopes to give us a solid diagnosis. We have no "umbrella" diagnosis now but his Genetics doc is certain there is some sort of chromosome abnormality.
Age 9: weight is 45-47 lbs & 3 ft. 9 inches.
