Genes affected
ALX1 (HGNC:1494): (ALX homeobox 1) The specific function of this gene has yet to be determined in humans; however, in rodents, it is necessary for survival of the forebrain mesenchyme and may also be involved in development of the cervix. Mutations in the mouse gene lead to neural tube defects such as acrania and meroanencephaly. [provided by RefSeq, Jul 2008]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.145T>A (p.C49S) alteration is located in exon 1 (coding exon 1) of the ALX1 gene. This alteration results from a T to A substitution at nucleotide position 145, causing the cysteine (C) at amino acid position 49 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
