Genes affected

DSCAML1 (HGNC:14656): (DS cell adhesion molecule like 1) The protein encoded by this gene is a member of the Ig superfamily of cell adhesion molecules and is involved in neuronal differentiation. The encoded membrane-bound protein localizes to the cell surface, where it forms aggregates that repel neuronal processes of the same cell type. [provided by RefSeq, Sep 2016]

The c.6231C>G (p.H2077Q) alteration is located in exon 33 (coding exon 33) of the DSCAML1 gene. This alteration results from a C to G substitution at nucleotide position 6231, causing the histidine (H) at amino acid position 2077 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
