Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.169A>G (p.I57V) alteration is located in exon 4 (coding exon 1) of the TMEM100 gene. This alteration results from a A to G substitution at nucleotide position 169, causing the isoleucine (I) at amino acid position 57 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
