Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.487G>A (p.A163T) alteration is located in exon 2 (coding exon 2) of the TMEM252 gene. This alteration results from a G to A substitution at nucleotide position 487, causing the alanine (A) at amino acid position 163 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
