Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2022The c.779A>G (p.N260S) alteration is located in exon 6 (coding exon 4) of the LYSMD4 gene. This alteration results from a A to G substitution at nucleotide position 779, causing the asparagine (N) at amino acid position 260 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
