Genes affected
TMPPE (HGNC:33865): (transmembrane protein with metallophosphoesterase domain) Predicted to enable hydrolase activity and metal ion binding activity. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
GLB1 (HGNC:4298): (galactosidase beta 1) This gene encodes a member of the glycosyl hydrolase 35 family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature lysosomal enzyme. This enzyme catalyzes the hydrolysis of a terminal beta-linked galactose residue from ganglioside substrates and other glycoconjugates. Mutations in this gene may result in GM1-gangliosidosis and Morquio B syndrome. [provided by RefSeq, Nov 2015]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 23, 2024 | The c.1274T>A (p.V425D) alteration is located in exon 2 (coding exon 1) of the TMPPE gene. This alteration results from a T to A substitution at nucleotide position 1274, causing the valine (V) at amino acid position 425 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
