Genes affected

FREM3 (HGNC:25172): (FRAS1 related extracellular matrix 3) This gene encodes an integral membrane protein containing numerous CSPG (chondroitin sulfate proteoglycan element) repeats and Calx-beta domains. The protein belongs to the family of FRAS1/FREM extracellular matrix proteins and may play a role cell adhesion. [provided by RefSeq, Feb 2017]

GUSBP5 (HGNC:42319): (GUSB pseudogene 5)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.99).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.333 is higher than 0.05.
