Genes affected

CRYL1 (HGNC:18246): (crystallin lambda 1) The uronate cycle functions as an alternative glucose metabolic pathway, accounting for about 5% of daily glucose catabolism. The product of this gene catalyzes the dehydrogenation of L-gulonate into dehydro-L-gulonate in the uronate cycle. The enzyme requires NAD(H) as a coenzyme, and is inhibited by inorganic phosphate. A similar gene in the rabbit is thought to serve a structural role in the lens of the eye. [provided by RefSeq, Jul 2008]

May 14, 2024

The c.875C>T (p.P292L) alteration is located in exon 8 (coding exon 8) of the CRYL1 gene. This alteration results from a C to T substitution at nucleotide position 875, causing the proline (P) at amino acid position 292 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
