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:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.44).
• BP6: Variant 6-5143954-A-G is Benign according to our data. Variant chr6-5143954-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1316696.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00526 (801/152332) while in subpopulation AFR AF= 0.0184 (764/41564). AF 95% confidence interval is 0.0173. There are 9 homozygotes in gnomad4. There are 374 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 9 AR gene
