Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.1127G>A (p.S376N) alteration is located in exon 14 (coding exon 13) of the SUPT20H gene. This alteration results from a G to A substitution at nucleotide position 1127, causing the serine (S) at amino acid position 376 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
