Genes affected

SOX5 (HGNC:11201): (SRY-box transcription factor 5) This 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. The encoded protein may play a role in chondrogenesis. A pseudogene of this gene is located on chromosome 8. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a DNA_binding_region HMG box (size 68) in uniprot entity SOX5_HUMAN there are 21 pathogenic changes around while only 0 benign (100%) in NM_006940.6
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SOX5. . Gene score misZ 3.1513 (greater than the threshold 3.09). Trascript score misZ 3.799 (greater than threshold 3.09). GenCC has associacion of gene with Lamb-Shaffer syndrome, developmental and speech delay due to SOX5 deficiency.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.927

The c.1848C>G (p.H616Q) alteration is located in exon 14 (coding exon 14) of the SOX5 gene. This alteration results from a C to G substitution at nucleotide position 1848, causing the histidine (H) at amino acid position 616 to be replaced by a glutamine (Q). This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. This missense alteration is located in a region that has a low rate of benign missense variation (Lek, 2016; Firth, 2009). This alteration is predicted to be deleterious by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
