Genes affected
RBMXL3 (HGNC:26859): (RBMX like 3) Predicted to enable mRNA binding activity and snRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be part of U12-type spliceosomal complex. [provided by Alliance of Genome Resources, Apr 2022]
LRCH2 (HGNC:29292): (leucine rich repeats and calponin homology domain containing 2) This gene encodes a member of the leucine-rich repeat and calponin homology domain-containing protein family. These family members contain multiple N-terminal leucine-rich repeats, in addition to a C-terminal calponin homology domain, a type of domain that mediates interactions with actin filaments. These proteins are conserved across animal species, and studies of a similar Drosophila protein indicate a function as a cytoskeletal scaffolding protein. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Sep 2011]

The c.184G>A (p.A62T) alteration is located in exon 1 (coding exon 1) of the RBMXL3 gene. This alteration results from a G to A substitution at nucleotide position 184, causing the alanine (A) at amino acid position 62 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
