Genes affected

LYRM4 (HGNC:21365): (LYR motif containing 4) The protein encoded by this gene is found in both mitochondria and the nucleus, where it binds cysteine desulfurase and helps free inorganic sulfur for Fe/S clusters. Disruption of this gene negatively impacts mitochondrial and cytosolic iron homeostasis. [provided by RefSeq, Sep 2016]

LYRM4-AS1 (HGNC:52055): (LYRM4 antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 6-5138726-T-C is Benign according to our data. Variant chr6-5138726-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 3031832.Status of the report is no_assertion_criteria_provided, 0 stars.
