Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2024The c.623C>T (p.T208M) alteration is located in exon 9 (coding exon 9) of the SUPT5H gene. This alteration results from a C to T substitution at nucleotide position 623, causing the threonine (T) at amino acid position 208 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
