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.

ROR1-AS1 (HGNC:40508): (ROR1 antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 3 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.

The c.499G>T (p.D167Y) alteration is located in exon 5 (coding exon 5) of the ROR1 gene. This alteration results from a G to T substitution at nucleotide position 499, causing the aspartic acid (D) at amino acid position 167 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
