General Information: The SALSA MLPA Probemix P013 ATRX is a research use only (RUO) assay for the detection of deletions or duplications in the ATRX gene, which is associated with Alpha-thalassemia X-linked mental retardation (ATRX) syndrome.

ATRX syndrome is characterized by distinctive craniofacial features - like microcephaly, telecanthus, widely spaced eyes, short nose -, genital anomalies, severe developmental delays, intellectual disability, hypotonia, skeletal anomalies, and alpha-thalassemia without molecular abnormalities of the alpha-globin gene complex. ATRX syndrome is inherited in an X-linked manner. The mother may be a carrier or the affected individual may have a de novo mutation. Female carriers have a 50% chance in each pregnancy of transmitting the ATRX pathogenic variant.

The ATRX gene encodes for the transcriptional regulator ATRX protein. The zinc finger domain functions as a transcription factor and the helicase domains function in the transcription process opening double-stranded DNA. In combination with other chromatin-associated proteins, the ATRX protein appears to play a role in chromatin remodelling, possibly silencing gene expression during development. The mutated ATRX protein downregulates the α-globin locus, resulting in thalassemia, and probably suppresses expression of other genes by disturbances in transcription and chromatin structure, leading to malformations and intellectual disability.

Probemix content: The SALSA MLPA Probemix P013-A2 ATRX contains 46 MLPA probes with amplification products between 130 and 490 nt. This includes 37 probes for the ATRX gene, with one probe for every exon and two probes for exons 9 and 35. In addition, nine reference probes are included and detect different regions on the X-chromosome. Complete probe sequences and the identity of the genes detected by the reference probes is available online (

This Probemix contains nine quality control fragments generating amplification products between 64 and 121 nt: four DNA Quantity Fragments (Q-fragments), two DNA Denaturation Fragments (D-fragments), one benchmark fragment, one chromosome X and one chromosome Y-specific fragment. More information on how to interpret observations on these control fragments can be found in the MLPA General Protocol and online at
