Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_Moderate BS2

The NM_001388459.1(FRMPD3):​c.290C>A​(p.Thr97Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00000366 in 1,092,494 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 3 hemizygotes in GnomAD. In-silico tool predicts 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. T97S) has been classified as Likely benign.

Genes affected

FRMPD3 (HGNC:29382): (FERM and PDZ domain containing 3) This gene encodes a protein that contains a PDZ (post synaptic density protein (PSD95), Drosophila disc large tumor suppressor (Dlg1), and zonula occludens-1 protein (zo-1) domain at the N-terminus followed by a FERM domain. The encoded protein is involved in signal transduction. The PDZ domain is thought to function in protein-protein interactions, mainly by binding to specific C-terminal peptides of other proteins. The FERM domain is found in proteins that are localized to the plasma membrane and are associated with the cytoskeleton. [provided by RefSeq, May 2017]

FRMPD3-AS1 (HGNC:41239): (FRMPD3 antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.25659898).
• BS2: High Hemizygotes in GnomAdExome4 at 3 gene
