Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2022The c.553G>A (p.V185M) alteration is located in exon 2 (coding exon 1) of the TMEM177 gene. This alteration results from a G to A substitution at nucleotide position 553, causing the valine (V) at amino acid position 185 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
