Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.581G>A (p.C194Y) alteration is located in exon 2 (coding exon 1) of the C1orf74 gene. This alteration results from a G to A substitution at nucleotide position 581, causing the cysteine (C) at amino acid position 194 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
