About PACS1

 

PACS1 Infographic-1 (1)PACS1 Syndrome is a very rare genetic condition caused by mutation of the PACS1 gene. It is NOT inherited from either parent (a “de novo” mutation) but it will be passed on to a patient’s child (“autosomal dominant”). PACS1 is a trans-Golgi-membrane traffic regulator that directs protein cargo and several viral envelope proteins. It is upregulated during human embryonic brain development and has low expression after birth. The first two cases were identified in early 2011 by doctors in the Netherlands. As of early 2017, there are just 40 cases that have been identified worldwide.

Diagnosis is typically done using full genome or exome sequencing. Both methods are expensive and not easily available. There are likely many more cases out there, that will eventually be reported as people learn about the condition, and testing becomes more affordable and available.

Parents of PACS1 children have found that most of our children have similar facial features such as:

– Widely spaced eyes and low-set ears
– Down-slanting eye corners and mild uni-brow
– Highly arched eyebrows and long eyelashes
– Round “button” nose with a flat arch
– Wide mouth with down-turned corners
– Thin upper lip and widely spaced teeth

Other common traits the parents have seen:

– Low muscle tone (“floppy baby”)
– Seizures (usually short and sporadic)
– Repetitive stimulation (similar to Autism Spectrum Disorders)
– Sensory over/under sensitivity (similar to Autism Spectrum Disorders)
– Motor planning difficulties (affects movement and coordination)
– Delayed physical and cognitive development
– Chewing and swallowing diffculties
– Digestion and/or bowel problems
– Slower growth resulting in lower height and weight

In combination, these traits affect walking, talking, feeding, and learning skills. No impact on life expectancy has been found. Currently there is no single “cure”.

The parents of children with PACS1 created this site to provide information on this rare syndrome and to provide resources to newly diagnosed families. If you have any questions please contact your primary care physician or PACS1information@gmail.com

  4. Hallo 🙂
    Unsere Tochter Nele ist 6 Jahre alt und wurde am 10.02.17 diagnostiziert. Wir sind schon ganz herzlich in der PACS1 Facebook Gruppe aufgenommen worden. Vielleicht gibt es ja noch Betroffene aus Deutschland, die kein Facebook haben und hier “gelandet” sind. Gerne könnt ihr uns kontaktieren!

    • Peguei o teste genético do meu filho , e deu como resumo ” uma variante provavelmente patogênica no gene PACS1″, esse artigo mostra algumas das características que meu filho tem, estou muito tranquila, mais gostaria de conversar com pais que tenham crianças com essa síndrome.

  5. Wow!! After reading the information on pacs1 it was like reading about my daughter. It’s quite an exciting thought that maybe after 4 years there’s a glimmer of hope. I’m not sure how easy it is to request a test but I will be asking.
