Lydia Sagath

Molecular scientist based in Helsinki, Finland.

I aim to be part of the advancements in the field of molecular medical genetics, with a specialization in disorders affecting the muscular system. The development of new diagnostic methods and uncovering the functional mechanisms of neuromuscular disorders lie in the center of my work.


Characterization of YBX3

A putative novel Nemaline myopathy causing gene

Variants in the Y-box binding protein 3 (YBX3) gene have been connected to Nemaline myopathy. To better understand the impact of these variants, we are working on localization and interaction studies of the wild-type protein and the variants. Part of the work is being done in collaboration with Stephan Lange's group in California.

Development of a Digital Droplet PCR based diagnostic method

Reaching the needed resolution in hard to reach regions

Titin and nebulin, two gigantic sarcomeric proteins, both contain segmental duplication regions in their sequences, and harbor both normal and pathogenic copy number variation. These blocks are challenging to analyze by both Comparative Genomic Hybridization array methods - therefore we are developing ddPCR based assays for the analysis of these regions. The method is under validation, and will be subject for a manuscript in the near future.

An extended Comparative Genomic Hybridization array for the diagnostics of neuromuscular disorders

To complement the diagnostic methods available

The extended CGH-array design that we developed covers 178 genes related to neuromuscular disorders, covered at a high tileage. The array constitutes a robust method for copy number variant analysis for diagnostics of neuromuscular disorder patients, and also covers the segmental duplication regions of both nebulin and titin.

Skills & Interests

Professional skills

My main skills and expertise lie in genomic copy number variation analysis (specifically aCGH and ddPCR) and cell culture based functional protein studies, including High Content Screening. To complement these, I study statistics and R to support my data analysis skills and university pedagogy to support my teaching interests. As a side project, I'm developing the new webpages for our reseach group (including HTML, CSS, PHP).

Language skills

  • Swedish, native
  • Finnish, native
  • English, proficient
  • French, proficient

Personal interests

In my free time I enjoy horseback riding and various forms of art - I also enjoy playing music myself (much to the disdain of my neighbors). I am an active member of the amateur choir It's a Kuoro and the student choir Symbioosin kuoro. My most recent infatuation is with scuba diving - I acquired my CMAS P1 in spring 2019 and went on to earn my NAUI Advanced Diver certificate in March 2020.
