Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.403G>A (p.A135T) alteration is located in exon 1 (coding exon 1) of the EFCC1 gene. This alteration results from a G to A substitution at nucleotide position 403, causing the alanine (A) at amino acid position 135 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
