Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_006574.4(CSPG5):​c.563G>A​(p.Gly188Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G188V) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 31)
• Consequence: CSPG5 NM_006574.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.232
• Publications: 38 publications found

Genes affected

CSPG5 (HGNC:2467): (chondroitin sulfate proteoglycan 5) The protein encoded by this gene is a proteoglycan that may function as a neural growth and differentiation factor. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2011]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.047734797).
