Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2024The c.1330C>T (p.R444W) alteration is located in exon 12 (coding exon 12) of the SCAF8 gene. This alteration results from a C to T substitution at nucleotide position 1330, causing the arginine (R) at amino acid position 444 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
