Coffin-Lowry syndrome and schizophrenia: a family report

Area of Science:

• Medical Genetics
• Clinical Dysmorphology
• Pediatric Neurology

Background:

• Coffin-Lowry syndrome (CLS) is a rare genetic disorder.
• CLS is characterized by intellectual disability, skeletal abnormalities, and distinct facial features.
• The genetic basis and phenotypic variability of CLS are areas of ongoing research.

Purpose of the Study:

• To report a multigenerational family exhibiting features consistent with Coffin-Lowry syndrome.
• To document the constellation of abnormalities observed in affected individuals.
• To contribute to the understanding of the phenotypic spectrum of Coffin-Lowry syndrome.

Main Methods:

• Clinical evaluation of affected family members.
• Detailed phenotypic assessment, including physical examination and skeletal surveys.
• Review of existing literature on Coffin-Lowry syndrome.

Main Results:

• A mother and four of her six children presented with a combination of mental handicap, abnormal facies, short stature, and skeletal abnormalities.
• Affected individuals displayed characteristic features such as soft, fleshy hands with tapering fingers.
• One daughter showed symptoms suggestive of schizophrenia, and one son had severe sensorineural deafness, expanding the known phenotype.

Conclusions:

• The reported family represents a significant addition to the cohort of individuals with Coffin-Lowry syndrome.
• The presence of schizophrenia-like symptoms and severe sensorineural deafness in affected members broadens the recognized clinical spectrum of CLS.
• Further research is warranted to elucidate the genotype-phenotype correlations and potential modifier genes in Coffin-Lowry syndrome.
