Genes affected

FXR1 (HGNC:4023): (FMR1 autosomal homolog 1) The protein encoded by this gene is an RNA binding protein that interacts with the functionally-similar proteins FMR1 and FXR2. These proteins shuttle between the nucleus and cytoplasm and associate with polyribosomes, predominantly with the 60S ribosomal subunit. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

FXR1 Gene-Disease associations (from GenCC):

• congenital myopathy

  Inheritance: AR Classification: STRONG Submitted by: G2P
• myopathy, congenital, with respiratory insufficiency and bone fractures

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
• myopathy, congenital proximal, with minicore lesions

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.02).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.785 is higher than 0.05.
