Genes affected

SOX4 (HGNC:11200): (SRY-box transcription factor 4) This intronless gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins, such as syndecan binding protein (syntenin). The protein may function in the apoptosis pathway leading to cell death as well as to tumorigenesis and may mediate downstream effects of parathyroid hormone (PTH) and PTH-related protein (PTHrP) in bone development. The solution structure has been resolved for the HMG-box of a similar mouse protein. [provided by RefSeq, Jul 2008]

ENSG00000283480 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a DNA_binding_region HMG box (size 68) in uniprot entity SOX4_HUMAN there are 11 pathogenic changes around while only 0 benign (100%) in NM_003107.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.989
• PP5: Variant 6-21594716-G-A is Pathogenic according to our data. Variant chr6-21594716-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 987399.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=1, Likely_pathogenic=1}.
