Genes affected

PALM (HGNC:8594): (paralemmin) This gene encodes a member of the paralemmin protein family. The product of this gene is a prenylated and palmitoylated phosphoprotein that associates with the cytoplasmic face of plasma membranes and is implicated in plasma membrane dynamics in neurons and other cell types. Several alternatively spliced transcript variants have been identified, but the full-length nature of only two transcript variants has been determined. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 19-726133-C-T is Benign according to our data. Variant chr19-726133-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 1941941.Status of the report is criteria_provided_single_submitter, 1 stars.
