Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.170A>G (p.K57R) alteration is located in exon 1 (coding exon 1) of the MANSC4 gene. This alteration results from a A to G substitution at nucleotide position 170, causing the lysine (K) at amino acid position 57 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
