Decoding the Genetic Mysteries of Cleft Palate with Ankyloglossia
Clefting of the palate alongside a tongue tied by a short frenulum is the subject, with research on TBX22, DNA damage response and Robin sequence mortality.
Partial LAMA2 Deficiency CMD: Merosin and Testing
Reduced laminin-α2 leaves muscle cells fragile in merosin-deficient CMD, with weakness and contractures; LAMA2 testing also allows prenatal diagnosis.
Decoding Coronary Artery Disease Development in HIV Patients: The Role of Genetic Testing
In people with HIV, the virus, antiretroviral therapy and standard risk factors all shape CAD risk, while imaging and genetic testing guide diagnosis and care.
Coronary Artery Disease: Genes, 9p21 and Risk Scores
The rs10757278 variant on chromosome 9p21, loci shared with psoriasis and RETN and IL1RL1 variants are among the genetic findings tied to CAD on this page.
Decoding the Genetic Mysteries of Coronary Artery Disease Susceptibility
A TaqI variant in the VDR gene, six SNPs from a Japanese population and TGFβ polymorphisms are the susceptibility findings covered, plus how risk is quantified.
Cracking the Code: Understanding Nonsyndromic Unicoronal Craniosynostosis Through Genetic Testing
Variants in SMAD6, TWIST1 and EFNB1 have been reported in nonsyndromic cases, and one study found no outcome difference between two treatment approaches.
Unraveling the Mysteries of X-Linked Deafness-5: Understanding, Diagnosing, and Using Genetic Testing
Mainly affecting males, DFNX5 is tied to SMPX, TIMM8A and PRPS1 mutations on the X chromosome; hearing tests and family history guide further genetic testing.
