Genes affected

PACS2 (HGNC:23794): (phosphofurin acidic cluster sorting protein 2) Predicted to enable transmembrane transporter binding activity. Involved in endoplasmic reticulum calcium ion homeostasis; mitochondrion-endoplasmic reticulum membrane tethering; and protein localization to plasma membrane. Acts upstream of or within protein localization to phagophore assembly site. Located in endoplasmic reticulum and mitochondrion. Implicated in developmental and epileptic encephalopathy 66.

BRF1 (HGNC:11551): (BRF1 RNA polymerase III transcription initiation factor subunit) This gene encodes one of the three subunits of the RNA polymerase III transcription factor complex. This complex plays a central role in transcription initiation by RNA polymerase III on genes encoding tRNA, 5S rRNA, and other small structural RNAs. The gene product belongs to the TF2B family. Several alternatively spliced variants encoding different isoforms, that function at different promoters transcribed by RNA polymerase III, have been identified. [provided by RefSeq, Jun 2011]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 14-105314177-G-A is Benign according to our data. Variant chr14-105314177-G-A is described in ClinVar as [Benign]. Clinvar id is 1289061.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0525 is higher than 0.05.
