Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2022The c.427C>T (p.H143Y) alteration is located in exon 3 (coding exon 2) of the TMEM248 gene. This alteration results from a C to T substitution at nucleotide position 427, causing the histidine (H) at amino acid position 143 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
