Genes affected

KL (HGNC:6344): (klotho) This gene encodes a type-I membrane protein that is related to beta-glucosidases. Reduced production of this protein has been observed in patients with chronic renal failure (CRF), and this may be one of the factors underlying the degenerative processes (e.g., arteriosclerosis, osteoporosis, and skin atrophy) seen in CRF. Also, mutations within this protein have been associated with ageing and bone loss. [provided by RefSeq, Jul 2008]

KL Gene-Disease associations (from GenCC):

• tumoral calcinosis, hyperphosphatemic, familial, 1

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• tumoral calcinosis, hyperphosphatemic, familial, 3

  Inheritance: AR, Unknown Classification: LIMITED Submitted by: Genomics England PanelApp, Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.541 is higher than 0.05.
