Genes affected

TLCD1 (HGNC:25177): (TLC domain containing 1) Involved in several processes, including membrane assembly; phospholipid homeostasis; and regulation of membrane lipid distribution. Located in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

TLCD1 links:

NEK8 (HGNC:13387): (NIMA related kinase 8) This gene encodes a member of the serine/threionine protein kinase family related to NIMA (never in mitosis, gene A) of Aspergillus nidulans. The encoded protein may play a role in cell cycle progression from G2 to M phase. Mutations in the related mouse gene are associated with a disease phenotype that closely parallels the juvenile autosomal recessive form of polycystic kidney disease in humans.

Collection Method:clinical testing

The c.187C>G (p.L63V) alteration is located in exon 1 (coding exon 1) of the TLCD1 gene. This alteration results from a C to G substitution at nucleotide position 187, causing the leucine (L) at amino acid position 63 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
