Genes affected
TMEM150B (HGNC:34415): (transmembrane protein 150B) This gene encodes a protein that belongs to the DRAM (damage-regulated autophagy modulator) family of membrane-spanning proteins. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.178A>G (p.N60D) alteration is located in exon 5 (coding exon 3) of the TMEM150B gene. This alteration results from a A to G substitution at nucleotide position 178, causing the asparagine (N) at amino acid position 60 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
