Genes affected

ARID3A (HGNC:3031): (AT-rich interaction domain 3A) This gene encodes a member of the ARID (AT-rich interaction domain) family of DNA binding proteins. It was found by homology to the Drosophila dead ringer gene, which is important for normal embryogenesis. Other ARID family members have roles in embryonic patterning, cell lineage gene regulation, cell cycle control, transcriptional regulation, and possibly in chromatin structure modification.

Collection Method: clinical testing

The c.112C>T (p.R38W) alteration is located in exon 2 (coding exon 1) of the ARID3A gene. This alteration results from a C to T substitution at nucleotide position 112, causing the arginine (R) at amino acid position 38 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
