Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 11, 2024The c.529C>T (p.H177Y) alteration is located in exon 5 (coding exon 3) of the TMEM68 gene. This alteration results from a C to T substitution at nucleotide position 529, causing the histidine (H) at amino acid position 177 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
