Genes affected
HYCC1 (HGNC:24587): (hyccin PI4KA lipid kinase complex subunit 1) The protein encoded by this gene may play a part in the beta-catenin/Lef signaling pathway. Expression of this gene is down-regulated by beta-catenin. Defects in this gene are a cause of hypomyelination with congenital cataract (HCC). [provided by RefSeq, Oct 2008]

Hypomyelination and Congenital Cataract Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 30, 2021This sequence change replaces glutamic acid with glycine at codon 395 of the FAM126A protein (p.Glu395Gly). The glutamic acid residue is highly conserved and there is a moderate physicochemical difference between glutamic acid and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with FAM126A-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
