Genes affected

ROR1 (HGNC:10256): (receptor tyrosine kinase like orphan receptor 1) This gene encodes a receptor tyrosine kinase-like orphan receptor that modulates neurite growth in the central nervous system. The encoded protein is a glycosylated type I membrane protein that belongs to the ROR subfamily of cell surface receptors. It is a pseudokinase that lacks catalytic activity and may interact with the non-canonical Wnt signalling pathway. This gene is highly expressed during early embryonic development but expressed at very low levels in adult tissues. Increased expression of this gene is associated with B-cell chronic lymphocytic leukaemia. Alternative splicing results in multiple transcript variants encoding different isoforms.

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 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), ROR1. . Gene score misZ 2.1715 (greater than the threshold 3.09). Trascript score misZ 3.1383 (greater than threshold 3.09). GenCC has associacion of gene with nonsyndromic genetic hearing loss, hearing loss, autosomal recessive 108, hearing loss, autosomal recessive.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.973
• PP5: Variant 1-64178248-G-C is Pathogenic according to our data. Variant chr1-64178248-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 437889.Status of the report is no_assertion_criteria_provided, 0 stars.
