Genes affected

LYAR (HGNC:26021): (Ly1 antibody reactive) Enables several functions, including DNA-binding transcription factor binding activity; identical protein binding activity; and transcription regulator inhibitor activity. Involved in several processes, including erythrocyte development; negative regulation of innate immune response; and regulation of transcription, DNA-templated. Located in nucleolus and nucleoplasm.

The c.370G>C (p.V124L) alteration is located in exon 6 (coding exon 4) of the LYAR gene. This alteration results from a G to C substitution at nucleotide position 370, causing the valine (V) at amino acid position 124 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
