Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2021The c.733G>A (p.V245I) alteration is located in exon 8 (coding exon 8) of the MARK1 gene. This alteration results from a G to A substitution at nucleotide position 733, causing the valine (V) at amino acid position 245 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
