Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.458G>A (p.R153Q) alteration is located in exon 2 (coding exon 2) of the TMEM178A gene. This alteration results from a G to A substitution at nucleotide position 458, causing the arginine (R) at amino acid position 153 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
