Genes affected

SOX21 (HGNC:11197): (SRY-box transcription factor 21) SRY-related HMG-box (SOX) genes encode a family of DNA-binding proteins containing a 79-amino acid HMG (high mobility group) domain that shares at least 50% sequence identity with the DNA-binding HMG box of the SRY protein (MIM 480000). SOX proteins are divided into 6 subgroups based on sequence similarity within and outside of the HMG domain. For additional background information on SOX genes, see SOX1 (MIM 602148).[supplied by OMIM, Apr 2004]

The c.817G>A (p.A273T) alteration is located in exon 1 (coding exon 1) of the SOX21 gene. This alteration results from a G to A substitution at nucleotide position 817, causing the alanine (A) at amino acid position 273 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
