Genes affected

PCLO (HGNC:13406): (piccolo presynaptic cytomatrix protein) The protein encoded by this gene is part of the presynaptic cytoskeletal matrix, which is involved in establishing active synaptic zones and in synaptic vesicle trafficking. Variations in this gene have been associated with bipolar disorder and major depressive disorder. Two transcript variants encoding different isoforms have been found for this gene.

PCLO Gene-Disease associations (from GenCC):

• pontocerebellar hypoplasia type 3

  Inheritance: AR Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Orphanet, Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=4.7973565E-5).
• BP6: Variant 7-82952543-C-T is Benign according to our data. Variant chr7-82952543-C-T is described in ClinVar as Benign. ClinVar VariationId is 1599232.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.457 is higher than 0.05.
