<unk>  can be extremely difficult to diagnose. While people are born with ALGS, it is almost always diagnosed later during childhood. The diagnosis can be difficult because the severity of the disease varies widely among patients. Some common clinical tests that are run in order to diagnose the disease include vertebral x-rays, heart exams to detect any defects such as a heart murmur, and a liver biopsy to detect liver disease or any precursors. If a patient presents with multiple symptoms such as jaundice, heart murmur, and the characteristic facial features discussed above (deep set eyes, broad brow, etc.), they are likely to be diagnosed with<unk> . A more calculated and specific diagnosis can be done with genetic testing. Next-generation sequencing can be utilized to detect single nucleotide polymorphisms (SNPs) in the affected gene(s). Multiplex ligation-dependent probe amplification (MLPA) can detect large deletions and/or insertions and microarray comparative genomic hybridization is used to improve the accuracy of MLPA.
