Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2021The c.1235C>T (p.S412F) alteration is located in exon 3 (coding exon 1) of the C17orf80 gene. This alteration results from a C to T substitution at nucleotide position 1235, causing the serine (S) at amino acid position 412 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
