Genes affected

CASP7 (HGNC:1508): (caspase 7) This gene encodes a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. The precursor of the encoded protein is cleaved by caspase 3 and 10, is activated upon cell death stimuli and induces apoptosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.15092891).
• BS2: High AC in GnomAd at 9 AD gene.

The c.143A>T (p.D48V) alteration is located in exon 3 (coding exon 2) of the CASP7 gene. This alteration results from a A to T substitution at nucleotide position 143, causing the aspartic acid (D) at amino acid position 48 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
