Genes affected

SOBP (HGNC:29256): (sine oculis binding protein homolog) The protein encoded by this gene is a nuclear zinc finger protein that is involved in development of the cochlea. Defects in this gene have also been linked to intellectual disability. [provided by RefSeq, Mar 2011]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.031421125).

The c.2349C>G (p.D783E) alteration is located in exon 6 (coding exon 6) of the SOBP gene. This alteration results from a C to G substitution at nucleotide position 2349, causing the aspartic acid (D) at amino acid position 783 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
