Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.491C>T (p.S164L) alteration is located in exon 7 (coding exon 6) of the SCAF1 gene. This alteration results from a C to T substitution at nucleotide position 491, causing the serine (S) at amino acid position 164 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
