Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.2117C>A (p.T706K) alteration is located in exon 18 (coding exon 18) of the SCAF8 gene. This alteration results from a C to A substitution at nucleotide position 2117, causing the threonine (T) at amino acid position 706 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
