Genes affected

JRKL (HGNC:6200): (JRK like) The function of this gene has not yet been defined, however, the encoded protein shares similarity with the human (41% identical) and mouse (34% identical) jerky gene products. This protein may act as a nuclear regulatory protein. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, May 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08092767).

The c.218C>T (p.P73L) alteration is located in exon 1 (coding exon 1) of the JRKL gene. This alteration results from a C to T substitution at nucleotide position 218, causing the proline (P) at amino acid position 73 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
