Genes affected
TMEM38B (HGNC:25535): (transmembrane protein 38B) This gene encodes an intracellular monovalent cation channel that functions in maintenance of intracellular calcium release. Mutations in this gene may be associated with autosomal recessive osteogenesis. [provided by RefSeq, Oct 2012]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.103C>A (p.R35S) alteration is located in exon 1 (coding exon 1) of the TMEM38B gene. This alteration results from a C to A substitution at nucleotide position 103, causing the arginine (R) at amino acid position 35 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
