Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.814C>T (p.P272S) alteration is located in exon 2 (coding exon 2) of the TMEM64 gene. This alteration results from a C to T substitution at nucleotide position 814, causing the proline (P) at amino acid position 272 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
