Genes affected

KERA (HGNC:6309): (keratocan) The protein encoded by this gene is a keratan sulfate proteoglycan that is involved in corneal transparency. Defects in this gene are a cause of autosomal recessive cornea plana 2 (CNA2).[provided by RefSeq, May 2010]

KERA Gene-Disease associations (from GenCC):

• cornea plana

  Inheritance: AR Classification: DEFINITIVE Submitted by: G2P
• cornea plana 2

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics
• congenital cornea plana

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.623 is higher than 0.05.
