Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 18, 2023The c.1102A>G (p.R368G) alteration is located in exon 9 (coding exon 9) of the TMEM44 gene. This alteration results from a A to G substitution at nucleotide position 1102, causing the arginine (R) at amino acid position 368 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
