Genes affected

RBM10 (HGNC:9896): (RNA binding motif protein 10) This gene encodes a nuclear protein that belongs to a family proteins that contain an RNA-binding motif. The encoded protein associates with hnRNP proteins and may be involved in regulating alternative splicing. Defects in this gene are the cause of the X-linked recessive disorder, TARP syndrome. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Mar 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RBM10. . Gene score misZ 4.4623 (greater than the threshold 3.09). GenCC has associacion of gene with TARP syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.25531968).

This sequence change replaces histidine, which is basic and polar, with proline, which is neutral and non-polar, at codon 367 of the RBM10 protein (p.His367Pro). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RBM10-related conditions. ClinVar contains an entry for this variant (Variation ID: 520756). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RBM10 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
