Genes affected
LIPN (HGNC:23452): (lipase family member N) The gene encodes a lipase that is highly expressed in granular keratinocytes in the epidermis, and plays a role in the differentiation of keratinocytes. Mutations in this gene are associated with lamellar ichthyosis type 4. [provided by RefSeq, Dec 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.109A>G (p.S37G) alteration is located in exon 2 (coding exon 2) of the LIPN gene. This alteration results from a A to G substitution at nucleotide position 109, causing the serine (S) at amino acid position 37 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
