Summaries for Chromosome 1q41-Q42 Deletion Syndrome

NIH Rare Diseases : 52 Chromosome 1q41-q42 deletion syndrome is characterized by a small, but variable deletion in a particular place on the long arm of one copy of chromosome 1 , usually spanning several genes . There have been variable features described in the literature, and individuals have ranged from being mildly to severely affected. Features may include poor feeding in infancy; developmental delay including delayed or absent speech; and moderate to severe intellectual disability . Other features may include hypotonia ; short stature ; seizures ; heart defects ; structural brain anomalies (most commonly underdevelopment of the corpus callosum ); genitourinary abnormalities ; cleft palate ; microcephaly ; vision problems; hearing loss ; and other abnormalities. Some may have characteristic facial features. Researchers have suggested the features are caused by disruption of at least four genes.

MalaCards based summary : Chromosome 1q41-Q42 Deletion Syndrome, also known as 1q41-q42 microdeletion syndrome, is related to pelger-huet anomaly and wdr26-related intellectual disability, and has symptoms including seizures An important gene associated with Chromosome 1q41-Q42 Deletion Syndrome is DEL1Q41Q42 (Chromosome 1q41-Q42 Deletion Syndrome). Affiliated tissues include brain, heart and eye, and related phenotypes are frontal bossing and intellectual disability
